Question

Estimate the difference:

$H\mathrm{T}\mathrm{O}724-587$

Answer 1

Step 1: Subtract the ones

Given : $H\mathrm{T}\mathrm{O}724-587$

As $7$ can not subtracted from $4$,

so, take $1$ carry from tens

now, $4$ becomes $14$ ( as $1$carry taken from tens )

First subtract ones $14-7=7$,

Write $7$ under ones column

Step 2: Subtract the tens

$2$ becomes $1$ in hundreds ( as $1$ carry taken by ones)

As $8$ can not subtracted from $1$,

so, take $1$ carry from hundreds

now, $1$ becomes $11$ ( as $1$carry taken from hundreds )

Next subtract tens $11-8=3$,

Write $3$ under tens column

Step 3: subtract the hundreds

$7$ becomes $6$ in hundreds ( as $1$ carry taken by tens)

Next subtract hundreds $6-5=1$,

Write $1$ under hundreds column

So we get,

$H\mathrm{T}\mathrm{O}\text{Carry over 6}1114\cancel{7}\cancel{2}\cancel{4}-587137$

Hence, the required solution is $137$
