Answer:
A) 5
B) -3
C) -3 or 3
D) -7 or 7
E) -4
Explanation:
a) The flea is jumping 4 to the right, which means you add 4 to 1.
b) The flea is jumping 4 to the left, which means you subtract 4 from 1.
c) If the flea is at 0, and is jumping 3 units, it can go either left or right, so you can both subtract 3 or add 3.
d) Like in question c, it is jumping 7 places, so it can either go right or left. So you can subtract or add 7 to/from 0.
e) The flea is to left of 0 by 4 spaces, which means that it's -4. And the absolute value of -4 is 4.
