Question

Estimate the difference:

$H\mathrm{T}\mathrm{O}805-585$

Answer 1

First ,Subtract the ones

Given : $H\mathrm{T}\mathrm{O}805-585$

First subtract ones $5-5=0$,

Write $0$ under ones column

Now, Subtract the tens

As $8$ can not subtracted from $0$,

so, take $1$ carry from hundreds

now, $0$ becomes $10$ ( as $1$carry taken from hundreds )

Next subtract tens $10-8=2$,

Write $2$ under tens column

Now, subtract the hundreds

$8$ becomes $7$ in hundreds ( as $1$ carry taken by tens)

Next subtract hundreds $7-5=2$,

Write $2$ under hundreds column

So we get,

$H\mathrm{T}\mathrm{O}\text{Carry over7}10\cancel{8}\cancel{0}5-585220$

Hence, the required solution is $220$
