| According to the condition of the task, you can make an equation.

Let’s take the first number as x and the second as y.

We get the following equation:

(x-y) * (x + y) = 0

This is the formula for the difference of squares. Let’s shorten it.

We get the following:

x ^ 2 – y ^ 2 = 0

It turns out that for the difference of these numbers to be equal to zero, both of these numbers must be the same.
