Chapter 4.3
Understanding integer division
What You'll Learn
Recognize division as finding how many equal groups fit into a total
Apply sign rules for integer division with positive and negative numbers
Visualize division problems using chip diagrams with red and blue counters
Determine that dividing two integers with identical signs yields a positive result
Calculate that dividing integers with different signs produces a negative answer
What You'll Practice
1
Drawing chip diagrams to represent positive and negative integer division
2
Dividing positive by positive integers using grouping methods
3
Dividing negative by negative integers to get positive quotients
