Basic Arithmetic covers fundamental mathematical operations including addition, subtraction, multiplication, and division.
Inverse operations are pairs of math actions that undo each other. When you add and then subtract the same number, you end up where you started!
If you add 5 and then subtract 5, you’re back to where you started. If you multiply by 2 and then divide by 2, you’re also back at the start!
Inverse operations help you check your work and solve math puzzles.
8 + 2 = 10 and 10 - 2 = 8
6 × 3 = 18 and 18 ÷ 3 = 6
Inverse operations undo each other and help you solve and check problems.
