Because that is how the opposite of a number is defined.

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.
When you add any number to its opposite, you are essentially combining a value with its negation. For example, if you take a number ( x ) and its opposite ( -x ), the operation can be expressed as ( x + (-x) ). This results in a cancellation of the values, leading to a sum of zero. This property illustrates the concept of additive inverses in mathematics.
Opposite faces always add to 7. Two is opposite five.

A number and its opposite,which add to zero.
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.

The number opposite -8.3 on the number line is 8.3. In mathematical terms, the opposite of a number is its additive inverse, which means that when you add a number and its opposite, you get zero. Therefore, -8.3 and 8.3 are opposites of each other.
On a six-sided cube die, the opposite side is the 2. (the opposite sides add to 7)
