Answer 1

Answer:

a) 9 × (100 + 3)

= 9 × 100 + 9 × 3

= 900 + 27

= 927

b) 12 × (100-2)

= 12 × 100 - 12 × 2

= 1200 - 24

= 1176

c) (101) × (104)

= (100 + 1) × ( 100+4)

= 100 × (100 +4) +1 ( 100 + 4)

= 100 × 100 + 100 × 4 + 1 × 100 + 1 × 4

= 10000 + 400 + 100 + 4

= 10504

d) (100-1) × (100+6)

= 100 × (100+6) - 1 × (100+6)

= 100 × 100 + 100 ×6 - 1×100 - 1 × 6

= 10000 + 600 - 100 - 6

= 10600 - 106

= 10494
