Danny says (7) and (-7) have different values
Mae says (7) and (-7) both equal 0
Luis says (7) and (-7) have the same value
Akkio says (7) and (-7) combine to make 0
Which person is correct? (with REASONING)
Akkio is correct.
In mathematics, the numbers 7 and -7 are called opposites or additive inverses of each other. When two numbers are additively inverse, their sum equals zero.
So, when 7 is added to -7, we get:
7 + (-7) = 0
Therefore, the statement made by Akkio is correct: "(7) and (-7) combine to make 0."
