Examples on multiplication of integers on different types of questions on integers are discussed here step by step.
1. Find the products of (-10) × 11
Solution:
(-10) × 11
= - (10 × 11)
= - 110
2. Find the products of 5 × (-7)
Solution:
5 × (-7)
= - (5 × 7)
= - 35
3. Find the products of (-115) × 8
Solution:
(-115) × 8
= - (115 × 8)
= - 920
4. Find the products of 9 × (-3) × (-6)
Solution:
9 × (- 3) × (- 6)
= - {(9 × (-3)} × (- 6)
= -(9 × 3) × (-6)
= - 27 × (-6)
= 27 × 6 = 162
5. Find the products of (-12) × (-13) × (-5)
Solution:
(- 12) × (- 13) × (-5)
= {(-12) × (-13)} × (-5)
= (12 × 13 ) × (-5)
= 156 × (-5)
= -(156 × 5 )
= -780
6. Evaluate the products of (-1) × (-2) × (-3) × (-4) × (-5)
Solution:
Since the number of negative integers in the product their product is odd. Therefore their product is negative.
(-1) × (-2) × (-3) × (-4) × (-5)
= -(1×2×3×4×5)
= -(2×3×4×5) [Since, 1 × 2 = 2]
=(6 × 4 × 5 ) [Since, 2 × 3 = 6 ]
= -(24 × 5 ) = -120 [Since, 6 × 4 = 24 ]
7. Evaluate the products of (3) × (-6) × (-9) × (-12)
Solution:
Since the number of negative integers in the given product is even. Therefore, their product is positive.
(-3) × (-6) × (-9) × (-12)
= (3 × 6 × 9 × 12)
= (18 × 9 × 12) [Since, 3 × 6 =18]
= (162 × 12) [Since, 18 × 9 =162]
= 1944
8. Find the value of 15625 × (-2) + (-15625) × 98
Solution:
15625 × (-2) + (-15625) × 98
= (-15625) × 2 + (-15625) × 98, [Since, 15625 × (-2) = -(15625 × 2) = (-15625 × 2)]
= (-15625) × (2 + 98), [Using: a × b + a × c = a × (b + c)]
= (-15625) × 100
= -(15625 × 100)
= -1562500
9. Find the value of 18946 × 99 - (-18946)
Solution:
18946 × 99 - (-18946)
= 18946 × 99 + 18946
= 18946 × 99 + 18946 × 1 [Since, 18946 = 18946×1]
= 18946 × (99 + 1) [Using: a × b + a × c = a × (b + c)]
= 18946 × 100
=1894600
10. Find the value of 1569 × 887 -569 × 887
Solution:
1569 × 887 – 569 × 887
= (1569 - 569) × 887 [Since, b × a - c × a = (b - c) × a]
= 1000 × 887
= 887000
