Question 1. Evaluate the following:

(i) (-7) × (-9) × (-11)
(ii) (-5) × 7 × (-6) × (-8)
(iii) (-1024) ÷ 32
(iv) (-216) ÷ (-12)

Answer:

(i) (-7) × (-9) × (-11)
= (63) × (-11)
= -693
(ii) (-5) × 7 × (-6) × (-8)
= -35 × (48)
= – 1680
(iii) (-1024) ÷ 32
= -1024/32
= – 32

(iv) (-216) ÷ (-12)
= -216/-12
= +18
= 18

Question 2. What will be the sign of the product if we multiply 39 negative integers and 98 positive integers?

Answer:

39 is odd and 98 is even.
Product of 39 negative and 98 positive integers will negative.

Question 3. Use the sign >, < or = in the box to make the following statements true:

(i) (-15) + 38 ……… 27 + (-50)
(ii) (-13) × 0 × (-5) …….. (-7) × (-6) × 14
(iii) (-18) ÷ (-3) …….. (-10) + (-15) + 31
(iv) (-5) × (-7) × (-10) …….. (-1400) ÷ (-4)

Answer:

(i) (-15) + 38 …….. 27 + (-50)
LHS = -15 + 38 = 23
RHS = 27 -50 = -23
(23) > (-23)

(ii) (-13) × 0 × (-5) ………… (-7) × (-6) × 14
LHS = -13 × 0 × (-5) = 0
And (-7) × (-6) × 14
RHS = 42 × 14 = 588
0 < 588
(iii) (-18) ÷ (-3) ……. (-10) + (-15) +31
LHS = -18 ÷ -3 = 6
RHS = (-10) + (-15) + 31 = -25 +31 = 6
6 = 6

Question 4. Is {(-45) ÷ (-15)} ÷ (-3) = (-45) ÷ [(-15) ÷ (-3)]?

Answer:

(-45) ÷ (-15) ÷ (-3)
LHS =  (-45/-15) ÷ (-3)
= 3 ÷ -3
= -1
And
RHS = -45 ÷ (-15/-3)
= -45 ÷ 5
= -9

(-1) ≠ -9
No, not equal.

Question 5. Simplify the following:

(i) (-7) + (-6) ÷ 2 – {(-5) × (-4) – (3 – 5)}
(ii) 11 – [7 – (5 – 3 (9 – 36)}].

Answer:

(i) (-7) + (-6) ÷ 2 – {(-5) × ( -4) – (3 – 5) }
= (-7) + (-6) ÷ 2 – [ +20 – (-2) ]
= (-7) + (-6) ÷ 2 – (20 + 2)
= (-7) + (-6/2) – 22
= ( -7) + (-3) – 22
= -7 – 3 – 22
= -32

(ii) 11 – [ 7 – { 5 – 3 ( 9 -3 – 6 ) }]
= 11 – [ 7 – { 5 – 3 ( 9 -3 + 6 ) }]

= 11 – [ 7 – ( 5 – 3 × 12}]

= 11 – [ 7 – ( 5 – 36 ) }]

= 11 – [ 7 – (-31) ]

= 11 – 38

= -27
