Question

2) Create three (3) examples of Front End Estimation for each of the followinga. Addition with Whole Numbersb. Subtraction with Whole Numbersc. Multiplication with Whole Numbersd. Division with Whole NumbersHint: All of your answers should be whole numbers except for division problems because numbers do not always divide evenly.

Answer 1

a. Addition with Whole Numbers

`5+2=7`

• b. Subtraction with Whole Numbers

`89-61=28`

• c. Multiplication with Whole Numbers

`8\cdot7=56`

d. Division with Whole Numbers

`(144)/(12)=12`

Step-by-step explanation

Whole numbers are any set of positive integers, with no fractional or decimal part.

• a. Addition with Whole Numbers

We can choose any number from 0 to ∞. For example:

`5+2=7`

• b. Subtraction with Whole Numbers

As the answer has to be a whole number then the first number has to be bigger than the second.

`89-61=28`

• c. Multiplication with Whole Numbers

Following the same rules as before:

`8\cdot7=56`

d. Division with Whole Numbers

In this case, the division has to be an exact number, no decimals:

`(144)/(12)=12`
