What are compatible numbers in math?

Compatible numbers are pairs of numbers that are easy to add, subtract, multiply, or divide mentally. When using estimation to approximate a calculation, replace actual numbers with compatible numbers. ... The numbers 513 and 299 are not compatible for addition, since the sum (812) cannot be easily calculated mentally.

In mathematics, compatible numbers are the numbers that are easy to add, subtract, multiply, or divide mentally. Compatible numbers are close in value to the actual numbers that make estimating the answer and computing problems easier.

i'm sure goog can you get that answer

the answer is (-8,-5)
