Question

Sean says that to add a number to -100 and still have -100 is to add zero. Candice says that she can add two numbers to -100 and still have -100. Who is correct and why ?

Answer 1

Sean is correct, because he adds 0 to -100, which equals to -100

I dont think Candice is correct however, since you cannot repeat the numbers
(and adding negative numbers is incorrect im assuming)

hope this helps

Answer 2

sean is correct and candice is wrong
