What is a reasonable estimate in math?
In math, reasonableness can be defined as checking to verify that the result of the solution or the calculation of the problem is correct or not, be either estimating or by plugging in your result to check it. A reasonable estimate does not exceed the original numbers in a problem.
Why do we estimate in math?

How do you know if an estimate is reasonable explain?
A reasonable estimate does not exceed the original numbers in a problem. For instance, in a division problem like 424 ÷ 4 − 10, we can check is our answer is reasonable or not, by estimating an approximate answer or by plugin gin using the division formula.
