Because that is how the opposite of a number is defined.
zero pair
The opposite of 260 is -260. In mathematical terms, the opposite of a number is its additive inverse, which means that when you add the number to its opposite, the result is zero. Therefore, 260 and -260 together equal zero.
The opposite of 2 is -2. In mathematics, the opposite of a number is its additive inverse, which means that when you add the two numbers together, the result is zero. Therefore, 2 + (-2) = 0.
The opposite of add is subtract.

If the type of solid (die) is a Platonic solid, then the opposite sides add to the number of faces plus one. For example, a cube's opposite sides add to seven.
Because of the definition of addition and subtraction. When looking at a real number line: when you add you move to the left or up, when you add the opposite of a number you move in the opposite direction.
