Common Questions
I'm taking Intermediate Algebra in high school. Is your Algebra 2 class compatible to my class?

Yes, Intermediate Algebra and Algebra 2 in high school are the same thing, just different naming. Or, if you are a student who is in a 10th grade Algebra 2 or sophomore Algebra 2 class, this is also the right course for you.

My teacher is using Glencoe Algebra 2. Can I use your site?

Most definitely! Our algebra 2 tutors cover all the topics you'll find in your textbook. Other algebra 2 textbooks, such as McDougal Littell Algebra 2 and Holt McDougal Algebra 2, we have all their materials covered too.

My class is called Algebra 2 and Trigonometry. Which course should I sign up for?

Our Algebra 2 help should cover all you need to know for your class. However, if you need more help on trig, check out our Online Trigonometry help too. Your subscription gives you unlimited access to all math help in all courses.

What are the prerequisites for Algebra 2?

A prerequisite for this course is either Algebra 1 or Basic Algebra, and after you mastered Algebra 2, your follow up course should be either Pre-Calculus or Trigonometry.

Jalen Casey

How can your algebra 2 tutors make concepts, such as matrices, how to solve system of equations algebraically, and factoring polynomials so easy to understand in your lessons? It's the best place to learn algebra 2! I started feeling bad for my math teacher. I am going to prepare my algebra 2 EOC with StudyPug.

Abby Powers

My son is taking algebra 2, and he is having trouble understanding topics related to logarithms in class. I couldn’t teach him because I was not familiar with math at all. I needed to look up algebra 2 for dummies sites for help. Luckily, we got the help from StudyPug. Their online tutorials not only give us the algebra 2 answers to questions, but also provide us with algebra 2 step-by-step solutions. Learning algebra 2 is not a problem for him anymore thanks to your tutors!

Shane Brooks

This website is my go-to place for algebra 2 help. I used it to do homework and prepare for the test on trigonometric function, and the results were great. I will definitely stick to the website for my algebra 2 final and beyond. I recommend this site to people who need online algebra 2 tutoring.

Sophie Moore

Watching video algebra two lessons online is just a much better learning experience than reading algebra two textbook. Love this site! this is the only site I want to learn algebra 2 with! Having great algebra 2 tutor on my side really makes a difference!

Nicolas Morales

Math in high school is hard. It is even more so for 10th grade algebra ii course. However, StudyPug's algebra 2 tutor helps me getting through all the difficult homework and tests with ease. I am now using it to prep my STAAR test.

Cam Donaldson

StudyPug covered the common core standards for algebra 2 so well. I found all the materials I need for homeschooling my daughter. Just having the glencoe algebra 2 skills practice answer key at the back of the book doesn’t really teach her how to solve the math questions. So, the algebra 2 step-by-step videos are particularly useful. I highly recommend this site! Best algebra 2 tutors for the buck.

Oscar Downing

My math teacher talks very fast in the sophomore algebra 2 class. There is not enough time for me to digest the difficult concepts. Therefore, I need algebra 2 tutoring so badly. Fortunately, I found StudyPug when I was looking for amsco’s algebra 2 and trigonometry answers online. I can review those tough to understand concepts with its step-by-step video lessons, and then do the practice questions. This site is just amazing for online algebra 2 help!

Alan Black

During my twelfth grade in senior high, I was quite anxious in taking math subjects in college because I’m sure it’ll be more difficult. But ever since I started doing my algebra 2 review on StudyPug and slader Larson algebra 2, I become more ready and confident to solve advanced algebra questions.

Lucas Peterson

It used to take me around 4 to 5 hours daily to solve math assignments during senior high on my twelfth year and it most of the times wears me down. My dad even downloaded a holt mcdougal algebra 2 teacher's edition pdf so that he could help me with my homework. But when I took the online algebra 2 review at StudyPug and practice answering algebra 2 worksheets, my math skills and knowledge improved continuously.

David Wittman

During senior high, my parents enrolled me at StudyPug to make math easier for me. My cousin also gave me a copy of Larson algebra 2 pdf to help me study. They both helped me be prepared for high-stakes tests and get ready for advanced algebra in college.

Samantha Patt

I was figuring out a way to help my daughter improve her math skills in algebra and I gave her a copy of the algebra 2 for dummies pdf and signed her up for an account at StudyPug. According to her, she understood the equations swiftly and solving algebra 2 problems are way easier.

Astrid Green

My sister lost a lot of marks in her algebra 2 final exam multiple choice questions section and she wants to pass the Regents Examinations. We asked her to take algebra 2 tutoring at StudyPug and get ready for the algebra 2 regents. Right now, she is now doing really well with factoring algebraic equations.

Angela Silverman

I found my son a copy of prentice hall algebra 2 textbook pdf and algebra 2 worksheets on StudyPug. They are really useful for my son on his twelfth year in high school. I am now sure he is prepared for advanced algebra class that's coming up soon.

Rita Smaby

As a mother, I always worry that my son won’t be able to grasp algebra 2 during his senior high. Every time before I helped him, I had to study the mcdougal littell algebra 2 teacher's edition pdf that I’ve found online, but his marks didn’t improve much and apparently it’s not enough. So, I looked for algebra 2 tutors that will help him come up with various methods to easily understand math. I found StudyPug online and my son enjoys his time solving algebra 2 problems on his own. I have more time on other stuff now!

Rose Martin

I can learn algebra 2 better with StudyPug and finish the quadratic equation worksheets so much faster now! I came across StudyPug when I was looking for a fundamental theorem of algebra calculator. I will keep using it for all my math classes. Love StudyPug.

Hugo Miller

It was always painful for me to do algebra 2 review only with the textbook and my math marks were never good. So, my mom told me to try out StudyPug and mangahigh algebra. I was skeptical at the beginning, but it turns out the algebra 2 tutors at StudyPug are somehow able to make math easy and not boring to me anymore. I will recommend it to my friends!

What is Algebra 2?

Algebra is the section of mathematics in which letters and symbols can be used to represent certain values/numbers in equations and formulae. Algebra 2 builds off the core principles taught in Algebra 1 and Basic Algebra, exploring complex numbers, functions, inequalities, linear equations, and more. In certain schools, Algebra 2 is often referred to as "Intermediate Algebra" but the two are essentially the same thing.

Our Algebra 2 lessons take an "algebra 2 for dummies" approach in that we make sure that all learners can take something away from our content. Whether you're a novice or well-versed in the world of Algebra, you'll find valuable information and resources throughout our algebra 2 tutoring platform.

With plenty of videos, exam prep materials, and valuable revision aides, StudyPug will be your very own algebra 2 tutor.

Is Algebra 2 Hard?

Initially, learning algebra 2 can be a daunting prospect, but once you have a firm grasp on the fundamentals, understanding algebra 2 can be made a lot easier and that's where StudyPug comes in!

Through an extensive collection of relevant and up-to-date algebra 2 tutorial content, we're able to deliver an easy to interpret set of step-by-step examples, providing you with a better understanding of the core principles and advanced elements of algebra. With 1000s of lessons to observe and relevant algebra exam prep materials that cover topics found in popular algebra textbooks, StudyPug is able to offer an exceptional collection of revision content.

Our online content will cover everything you can expect to be taught in the classroom as well as the content in textbooks not covered by your teachers. To further help you tackle algebra 2, our resources are accessible whenever you require them, working alongside your schedule and providing 24/7 help and guidance to better help you revise and prepare for upcoming exams.

What Comes After Algebra 2?

Upon successfully completing a course in Algebra 2 (usually taken alongside Trigonometry), most students are then adequately prepared to take on a course in Precalculus. Study Pug provides in-depth revision aides and videos for both trigonometry and Precalculus so that you can efficiently transition from course to course with ease.

This is made possible through the structuring of our content. Each course considers the content from previous lower level courses and the courses that will follow. This insures that you're never left entering a new course unprepared and unable to make the most of the content. Instead, you'll be better prepared with context and the relevant groundwork needed to build upon your level of understanding.

Additionally, upon completing Algebra 2, you may find that your problem solving skills outside of class have started to improve. This can be tremendously beneficial, because whether you know it or not, we use algebra in our daily lives more than we actually think we do.

What Grade is Algebra 2?

Algebra 2 or "intermediate algebra" is usually taught to students in 11th grade. With that being said, you don't need to be in 11th grade to benefit from our content. StudyPug caters to all learners regardless of their entry-point. Whether you're in 11th grade and need help with algebra 2 tests, or returning to education and need a brief refresher, StudyPug has the revision resources for you.

If you're currently studying algebra 1 or "basic algebra", consider using our online revision resources as they will not only assist you in your upcoming exams but they are also structured to help you seamlessly transition into our algebra 2 content.

What Do You Learn in Algebra 2?

Throughout algebra 2, you'll learn how to identify functions, solve absolute value equations, determine the number of solutions to linear equations, explore systems of inequalities, complex numbers, multiplying radicals and much more.

To help you better understand these various topics and to best prepare you for your upcoming exams, our revision materials have been designed to accurately reflect the up-to-date content found in the following popular algebra textbooks:

∙\bullet Algebra with Pizzazz
∙\bullet Holt McDougal Algebra 2
∙\bullet Glencoe Algebra 2
∙\bullet Prentice Hall Algebra 2
∙\bullet McDougal Littell Algebra 2
∙\bullet Big Ideas Math Algebra 2

If you've struggled to digest the language within these books, our team of mathematics tutors have broken down the key talking points of these textbooks and have expertly delivered them in an easy to understand format that you can pause, fast-forward, and rewind. By offering you an unprecedented level of video content to review, we're able to provide you with relevant study content that you're able to tackle at your own pace, delivering an easy practice solution that can dramatically improve your exam success rate.

As an introduction to our platform and to truly experience the benefits of our resources, consider sampling a few of our free lessons in the following areas of Algebra 2:

I'm taking Algebra 2, and I was doing okay. But then my friend told me about you guys saying it's an easy way to boost the math mark, so I tried. I am glad I did. I did very well in my last math test. Now I use your videos as a preview of my math class as well as for test prep.

Grieg Hughes
Algebra 2, Preston High, New York, NY

Math is always hard for me. I had math tutors before but it didn't work out so well because they are all very busy and expensive. I tried StudyPug for your free trial and I knew I have finally found the solution. You have examples just like the ones in my Algebra exam and homework. I use you guys all the time for homework and exams.

Jasmine Knight
Algebra 2, Littleton High, Denver, CO

I like studying at my own pace, especially when studying for harder courses like Algebra 2, but it seems impossible. The 24/7 access to your lessons gives me the freedom to learn in my way. I don't have to wait for teachers at school to get help. I am now able to study at nights with my computer.
