2 600 000 – 24 750 – 6 098 =

Method 1
9 9 9 14 Subtract two numbers
5 10101010 6 15 1 410 first before subtracting
6 0 0 0 0 0 5 7 5 2 5 0 the next number.
– 2 4 7 5 0 – 6 0 9 8
5 7 5 2 5 0 5 6 9 1 5 2

Method 2 When 1 is subtracted
from both numbers,

600 000 – 24 750 = the difference is
−1 −1 5 9 9 9 9 9 the same.
− 2 4 7 4 9
599 999 – 24 749 =
5 7 5 2 5 0

6 15 1 4 10
5 7 5 2 5 0
– 6 0 9 8
5 6 9 1 5 2

600 000 – 24 750 – 6 098 = 569 152

3 Subtract 43 195 and 178 from 305 608.

305 608 – 43 195 – 178 =
12
5 10 2 10 3 210
3 0 5 6 0 8 3 0 5 4 3 0
– 1 7 8 – 4 3 1 9 5
3 0 5 4 3 0 2 6 2 2 3 5

Now use method 1 as in example 2.
Are the answers the same?

305 608 – 43 195 – 178 = 262 235
