First of all, the calculator calculates, the percentage of a given number. I.e. a given number A is taken as 100%, as a result, we have a number C that is B percent of A.

Furthermore, the problem is getting complicated. Assume, we have a number A, which is the remainder of subtracting B percent of some original value, which is 100%. For example, you may determine your taxes amount by net salary and taxes rate.

The final problem is formulated as follows: here is some number A, consisting of the initial number and the percentage of B added to that number. It’s required to determine the percentage amount E. The similar problem is solved by every accountant when they calculate input VAT of the gross purchase amount.
