Answer 1

Answer:

a) 125 X 4 X 463 X 79 X 8

500 X 463 X 79 X 8

231500 X 632 = 146308000

b) 473 + 628 + 527 + 372

1101 + 899 = 2000

c) 800 X 45678 X 250 X 125 X 400

800 X 250 X 45678 X 125 X 400

200000 X 5709750 X 400

200000 X 2283900000 = 456780000000000

d) 725 X 1002

725 X (1000 + 2)

725 X 1000 + 725 X 2

725000 + 1450

= 726450

e) 998 X 989 = 987022
