Question

Find the difference between 900 and 247

Answer 1

The difference is that 900 is bigger than 247

Answer 2

`653`

Explanation:

we know that

the difference between
`900` and
`247` is equal to subtract
`247` from
`900`

so

`900-247`

remember that

`247=200+40+5+2`

substitute in the expression above

`900-247=900-(200+40+5+2)`

`=900-200-40-5-2` ------>
`=(900-200)-40-5-2`

`=700-40-5-2` ----->
`=(700-40)-5-2`

`=660-5-2` ----->
`=(660-5)-2`

`=655-2`

`=653`
