Question

If the number of steps moved down is represented by
negative integers and the number of steps moved up by
positive integers, represent his moves in part (i) and (ii)
by completing the following: (a)- 3 + 2 - ... = - 8
(b) 4-2+... = 8. In (a) the sum (-8) represents going
down by eight steps. So, what will the sum 8 in (b)
represent?​

Answer 1

Answer:

-3+2-...=-8

(a)2-x=-5

-x=-7

x=7

-3+2-7=8

-1-7=-8

-8=-8

8=8

(b)4-2+...=8

2+x=8

x=6

4-2+6=8

2+6=8

8=8
