Set of two opposite numbers that equal 0 when combined

Answer 1

A set of two opposite numbers that equal 0 when combined is any pair of numbers where one is the negative version of the other. For example:

• \( 5 \) and \( -5 \)
• \( 3 \) and \( -3 \)
• \( 10 \) and \( -10 \)

When you add these pairs together, they always equal 0:

• \( 5 + (-5) = 0 \)
• \( 3 + (-3) = 0 \)
• \( 10 + (-10) = 0 \)

In general, for any number \( x \), its opposite \( -x \) will satisfy this condition.
