What are Numbers?

A number is an arithmetic value used for representing the quantity and used in making calculations.

Given that Jan doubled her starting number, added 5, subtract 7, divided by 3, then squared the result.

Let her original number be x

Therefore, {(2x +5 - 7)/3}² = 36

{(2x -2)/3}² = 36

(2x -2)/3 = 6

2x - 2 = 18

2x = 20

x = 10

Hence, Jan's starting number was 10.
