Much like any other types of numbers (i.e. whole numbers, real numbers, natural numbers ...etc.), we can apply different types of operations on complex numbers. In this section, we will learn how to perform addition and subtraction on complex numbers.

- 1.Adding complex numbersa)$(3+4i)+(9+3i)$b)$(\frac{1}{2}-3i)+(-2+2i)+(5i+1)$c)$(6-5i)+(-4+7i)+(4i-2)$
- 2.Subtracting complex numbersa)$(7+9i)-(5+i)$b)$(1-3i)-(\frac{1}{6}+2i)-(\frac{1}{3}-i)$c)$(10-12i)-(-4-10i)+2i$
- 3.Adding/subtracting complex numbers graphically

$(2+2i)+(3+i)$
