Question

1. Find the value of the following by simplifying.
(a) 1569 x 887 - 569 x 887
(b) 18946 x 99-(-18946)
(c)(-8) X (10-5-43 +98)
(d) 29945 x 99 -(-29945)
(e) 2847 x 327 + (-847) x 327​

Answer 1

Step-by-step explanation:

(a) 1569 × 887 - 569 × 887

= 887(1579 - 579)

= 887 × 1000

= 887000

(b) 18946 × 99 - (-18946)

= 18946(99 - [-1])

= 18946(99 + 1)

= 18946(100)

= 1894600

(c) -8 × (10 -5 - 43 +98)

= -8 × (10 - 48 + 98)

= -8 × (10 + 50)

= -8 × 60

= -480

(d) 29945 × 99 - (-29945)

= 29945(99 - [-1])

= 29945(100)

= 2994500

(e) 2847 × 327 + (-847) × 327

= 327(2847 - [-847])

= 327(2847 - 847)

= 327(2000)

= 654000
