From the figures below, what can you conclude about the magnitudes of a and b compared. Class 7

From the figures below, what can you conclude about the magnitudes of a and b compared to each other, and what are their directions? Remember to start from 0. Class 7

Question 1.

Solution:

+ a-b (Negative direction)

Question 2.

Solution:

+ a - b (Positive direction)

Question 3.

Solution:

- a + b = 0

Question 2.

Using tokens, argue out the following statements. Class 7

(a) 7 - 18 = 7 + (- 18) (additive inverse of 18 is - 18)

(b) 4 - (- 12) = 4 + 12 (additive inverse of-12 is 12)

Solution:

Note: Do as directed.

(a) -11

(b) 16
