Answer 1

Using mental maths to solve the problem of 8.02 - 5.98 gives a difference of 2.04.

What is mental maths?

Mental mathematics is the method of working out maths calculations and solving problems in one's head (mentally) without writing them down or using calculators.

Mental maths provides a quick way of arriving at arithmetical solutions without mathematical tools.

Data and Calculations:

First value =       8.02

Second value = 5.98

Difference =      2.04

The mental method used to solve the problem is the removal of the decimal points, thus making the values look like these whole integers:

First value =       802

Second value = 598

Difference =      204

After obtaining the difference as 204, the two decimal places are replaced to arrive at the final answer.

Thus, using mental maths to solve the problem of 8.02 - 5.98 gives a difference of 2.04.
