How to use inverse operations to check additions
In this topic you are asked to select the correct inverse operation to use to check the given addition sum.
Inverse operations are pairs of operations that "undo" each other. For example, addition and subtraction are inverse operations, as are multiplication and division. To use inverse operations to check addition sums, you can perform the opposite operation to the addition, which should result in the original number you started with.
Let's say you have the addition problem: 25 + 7 and your answer is 32.
To check this problem using inverse operations, you can perform the opposite operation to addition, which is subtraction. So, you can subtract 7 from the answer to get back to the original number:
25 + 7 = 32
32 - 7 = 25
If the answer you get from subtracting the two numbers is the same as the number you started with (in this case, 25), then you know that your original addition problem was correct.
You can use inverse operations to check more complex addition problems. For example:
96 + 14 = 110
110 - 14 = 96
Notes on the topic: Check additions using inverse operations
In each question you are given an addition equation. You are asked to choose from a selection of 3 equations the inverse equation that will confirm the addition is correct.
