e. Inverse Operations.

Answer 1

When you adjust one number and change another number in the problem to make a computation easier, you use compatible numbers.

Step-by-step explanation:

When you adjust one number and change another number in the problem to make a computation easier, you use compatible numbers.

Compatible numbers are numbers that are easy to work with mentally and give a similar result to the original problem. For example, if you have the problem 245 + 127, you can adjust the numbers to 250 + 125, which are compatible numbers that make the computation easier.

Using compatible numbers is a helpful strategy to simplify calculations and get a reasonably accurate estimate of the answer without needing to perform complex calculations.
