Describe what happens when a number is added to its opposite.
Write an equation that shows a number c being added to its opposite.
When a number is added to its opposite, the result is always zero. This occurs because the opposite of a number is a value that, when added to the original number, cancels it out completely.
For example, if we take the number 5 and add its opposite, -5, the sum would be 0:
5 + (-5) = 0
In general, the equation that shows a number c being added to its opposite can be written as:
c + (-c) = 0
