Question

Can someone explain to me why this is supposed to be 21 and not -21

Answer 1

a subtraction symbol and a negative number next each other basically changes to addition. So in this example, -2 - -17 is the same as saying -2 + 17 which = 15. 15 - -6 is the same as 15 + 6 which is 21.


hope that helps! :)

Answer 2

21

Explanation:

The reason why the answer is 21 is because a minus with minus makes a positive.

-2 - -17 - -6

-2 + 17 + 6

15 + 6

= 21
