Negative bracket negative 2 equals what?

In mathematics, the symbol "-" represents the opposite number of a given number. When we enclose a number in brackets and add a negative sign in front of the brackets, we are essentially finding the opposite number of that value. Therefore, negative bracket negative 2 means finding the opposite number of 2.

The opposite number of 2 is a number that, when added to 2, results in 0. In other words, negative bracket negative 2 plus 2 equals 0. We can verify this result using simple arithmetic: -2 + 2 = 0. Hence, negative bracket negative 2 equals 0.
