Question

Find the value of
A) 1487 x 327 + (-487) x 327
B) 28945 x 99 - (28945)​

Answer 1

(i) We have,

1487 × 327 + (- 487) × 327

= 486249 – 159249

= 327000

(ii) We have,

28945 × 99 - (- 28945)

= 2865555 – 28945

= 2894500

Answer 2

Answer:

a) 1487×(327)+−(487)×327

=(1000+487)×(327)+(−487)×327

=327,000+487×327−487×327

=327,000

b) 28945*99+28945*1

28945 (99+1)

28945*100

=2894500 Ans.
