Q. 33.7( 7 Votes )

Simplify:(i) 100(100 – 3) – (100 × 100 – 3);(ii) (20–(2011–201) + (2011–(201–20))

Answer :

(i) 100(100 – 3) – (100 × 100 – 3)

= 100 × 100 - 100 × 3 – 100 × 100 + 3

= - 300 + 3 (cancellation property)

= - 297

(ii) (20 – (2011 – 201) + (2011– (201 – 20))

= 20 - 2011 + 201 + 2011 – 201 + 20

= 40 (cancellation property)
