Question

Estimate the difference:

$H\mathrm{T}\mathrm{O}932-817$

Answer 1

Step 1: Subtract the ones

Given : $H\mathrm{T}\mathrm{O}932-817$

As $7$ can not subtracted from $2$,

So, take $1$ carry from tens

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

First subtract ones $12-7=5$,

Write $5$ under ones column

Step 2: Subtract the tens

$3$ becomes $2$ in hundreds ( as $1$ carry taken by ones)

Next subtract tens $2-1=1$,

Write $1$ under tens column

Step 3: subtract the hundreds

Next subtract hundreds $9-8=1$,

Write $1$ under hundreds column

So we get,

So we get,

$H\mathrm{T}\mathrm{O}\text{Carry - over}2129\cancel{3}\cancel{2}-817115$

Hence, the required solution is $115$
