Question

Are the expressions -5+-2 and -5-2 equivalent ? why or why not? Explain and show your work

Answer 1

yes

Explanation:

-5 + -2 = -7

-5-2 = -7

If you subtract from a negative number, the subtraction turns into a plus sign and the numeral after the subtraction changes from a positive to a negative or a negative to a positive so -5-2 would turn into -5+-2
