To find those numbers, we need to build some sort of equation from the description and solve.
00:13
So we can work through this sentence or this description one piece at a time.

The first part says the square of the difference between a number and three.
00:23
Square should make you think of something with the exponent two.
00:29
What comes next is that something.
00:31
So the square of the difference between a number and three.
