Final answer:
In mathematics, to undo an accomplished operation you perform the opposite or inverse operation: addition is undone by subtraction, subtraction by addition, multiplication by division, and division by multiplication.
Explanation:
In mathematics, when you want to undo an operation, you perform its inverse operation. Here is how you undo the four basic mathematical operations:
- Addition is undone by subtraction. For instance, if you add 5 to a number and want to undo it, you subtract 5 from the result.
- Subtraction is undone by addition. For instance, if you subtract 7 from a number and want to undo it, you add 7 to the result.
- Multiplication is undone by division. For example, if you multiply a number by 3 and want to undo it, you divide the result by 3.
- Division is undone by multiplication. For instance, if you divide a number by 4 and want to undo it, you multiply the result by 4.
