Question

Find the difference:

$\mathrm{Th}\mathrm{H}\mathrm{T}\mathrm{O}5162-1644$

Answer 1

Step 1: Subtract the ones digits

Given , $\mathrm{Th}\mathrm{H}\mathrm{T}\mathrm{O}5162-1644$

As $2$ is lesser than $4$, we can not subtract directly

Take $1$ carry from tens ,

Now, $2$ becomes $12$ in ones place ( Extra $1$ carry from tens )

First subtract ones $12-4=8$,

Write $8$ under ones column

Step 2: Subtract the tens digits

$6$ becomes $5$ in tens place ( as $1$ carry taken by ones)

Next subtract tens $5-4=1$,

Write $1$ under tens column .

Step 3: Subtract the hundreds digits

As $1$ is lesser than $6$, we can not subtract directly

Take $1$carry from thousands ,

Now, $1$ becomes $11$ in hundreds place

Next subtract hundreds $11-6=5$,

Write $5$ under hundreds column .

Step 4: Subtract the thousands digits

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

And finally subtract thousand $4-1=3$

So we get,

$\mathrm{Th}\mathrm{H}\mathrm{T}\mathrm{O}5162-16443518$

Hence, the required solution is $3518$.
