Because that is how the opposite of a number is defined.
zero pair
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.
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.
Because that is how the opposite of a number is defined.
zero pair
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)
TRUEAnd when you add them together, you get zero.
TRUEAnd when you add them together, you get zero.
The opposite sides of dice always add up to seven, therefore your answer is six
