Question 10 Exercise 1.1

A monkey jumps 3 steps down and then jumps back 2 steps up.

If the number of steps moved down is represented by negative integers and the number of steps moved up by positive integers represent the monkey's moves by completing the following:

– 3 + 2 – ______= – 8.

Select the correct option

From the question, it is given that, if the number of steps moved down is represented by negative integers and the number of steps moved up by positive integers.

Monkey jumps 3 steps down and then jumps back 2 steps up

= – 3 + 2 – _________ = – 8

Then LHS = – 3 + 2 – 3 + 2 – 3 + 2 – 3 + 2 – 3 + 2 – 3

= – 18 + 10

= – 8

RHS = -8

Therefore, the correct answer is: – 3 + 2 – 3 + 2 – 3 + 2 – 3 + 2 – 3
