Question

Estimate the difference:

$H\mathrm{T}\mathrm{O}677-425$

Answer 1

Step 1: Subtract the ones digits

Given , $H\mathrm{T}\mathrm{O}677-425$

First subtract ones $7-5=2$,

Write $2$ under ones column

Step 2: Subtract the tens digits

Next subtract tens $7-2=5$,

Write $5$ under tens column

Step 3: Subtract the hundreds

Next subtract hundreds $6-4=2$,

Write $2$ under hundreds column

So we get,

$H\mathrm{T}\mathrm{O}677-425252$

Hence, the required solution is $252$.
