Question

Estimate the difference:

$H\mathrm{T}\mathrm{O}572-196$

Answer 1

Step 1: Subtract the ones

Given : $H\mathrm{T}\mathrm{O}572-196$

As $6$ can not subtracted from $2$,

so, take $1$ carry from tens

now, $2$ becomes $12$ ( as $1$carry taken from tens )

First subtract ones $12-6=6$,

Write $6$ under ones column

Step 2: Subtract the tens

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

As $9$ can not subtracted from $6$,

so, take $1$ carry from hundreds

now, $6$ becomes $16$ ( as $1$carry taken from hundreds )

Next subtract tens $16-9=7$,

Write $7$ under tens column

Step 3: subtract the hundreds

$5$ becomes $4$ in hundreds ( as $1$ carry taken by tens)

Next subtract hundreds $4-1=3$,

Write $3$ under Hundreds column

So we get,

$H\mathrm{T}\mathrm{O}\text{Carry over}41612\cancel{5}\cancel{7}\cancel{2}-196376$

Hence, the required solution is $376$
