*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.

*Rounding numbers means adjusting the digits to make rough calculations easier. The result will be an estimated answer rather than a precise one.

According to the previous definitions, we can conclude:

_Both ways give an approximate solution.

_One way may give an estimate that is closer to the actual solution than the other method
