Question

Cecil started from point A and moved according to the expression 8+(-5)+7+6+(-7)+5+(-8).What one additional step does Cecil need to in order to return to the starting point? CAN SOMEONE PLEASE HELP ME

Answer 1

This may look difficult but really it is just addition and subtraction. So first of all the negative numbers EX: (-5),  those are easy if it says add negative 5. its the same as subtraction 5. Its easier if you use a number line. So the problem 8+(-5)+7+6+(-7)+5+(-8) is equal to 6. So if the objective is to get the number to 0, you can subtract 6 (or add negative 6). If the objective is to get back to 8 (Since that is technically point A though it is unclear) then you need to add 2 (or subtract negative 2).  Viola!

Answer 2
