Using the token interpretation, find the values of: (a) 3 × (- 2); (b) (- 5) × (- 2): Class 7

Using the token interpretation, find the values of: (a) 3 × (- 2); (b) (- 5) × (- 2): Class 7

Question 1.

Using the token interpretation, find the values of: Class 7

(a) 3 × (- 2)

(b) (- 5) × (- 2)

(c) (- 4) × (- 1)

(d) (- 7) × 3

Solution:

Note : Do as directed.

(a) -6

(b) 10

(c) -4

(d) -21

Question 2.

If 123 × 456 = 56088, without calculating, find the value of: Class 7

(a) (- 123) × 456

(b) (- 123) × (- 456)

(c) (123) × (-456)

Solution:

(a) -56088

(b) 56088

(c) -56088

Question 3.

What integer do we get as the final answer in each case? Do we get different answers because the sets look different, or the same answer because they all represent - 2? Class 7

Solution:

Same answer.

Question 4.

Check this for 5 × 4, by taking different token sets corresponding to 4. Class 7

Solution:

Note : Do as directed.

5 × 4 = 20.
