Answer:

Question 10. 

(i) How many integers are there between -15 and -7 ?

(ii) How many integers are there between -6 and 3?

(iii) How many whole numbers are there between -6 and 6?

(iv) How many negative integers are there between -7 and 4?

Answer:

(i) 7

(ii) 8

(iii) 6

(iv) 6

Question 11: Evaluate the following.

(i) | 13 – 5 |

(ii) |5 – 13|

(iii)  |-11| + |9|

(iv) |-8| + |-6|

(v) |7| – |-3|

(vi) |-19| – |-13|

Answer:

(i) | 13 – 5 |

13 – 5 = 8

(ii) |5 – 13|

= |-8|

so |-8| = 8

(iii)  |-11| + |9|

|-11| = 11

|9| = 9

11 + 9 = 20

(iv) |-8| + |-6|  = 6

|-8| = 8

|-6| = 6

8 + 6 = 14

(v) |7| – |-3|

so 7 – 3 = 4

(vi) |-19| – |-13| = 13

so 19 – 13 = 6

(vi) -30 …………… -19

Answer:

(i) -3 < 7

(ii) 0 > -2

(iii)  -10 > -11

(iv) -6 < -2

(v) -5 > -13

(vi) -30 < -19
