Question

Estimate the difference:

$H\mathrm{T}\mathrm{O}710-535$

Answer 1

Step 1: Subtract the ones

Given : $H\mathrm{T}\mathrm{O}710-535$

As $5$ can not subtracted from $0$,

so, take $1$ carry from tens

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

First subtract ones $10-5=5$,

Write $5$ under ones column

Step 2: Subtract the tens

$1$ becomes $0$ in hundreds ( as $1$ carry taken by ones)

As $3$ can not subtracted from $0$,

so, take $1$ carry from hundreds

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

Next subtract tens $10-3=7$,

Write $7$ 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,

$H\mathrm{T}\mathrm{O}\text{Carry over 6}1010\cancel{7}\cancel{1}\cancel{0}-535175$

Hence, the required solution is $175$
