Question

If $378$ is taken away from $645$, then the difference will be equal to

Answer 1

Here, to find the difference, we need to subtract $378$ from $645$.

Step 1:
$\because 1\text{ten}=10\text{ones}$
In number 645, We will borrow one ten from 4 tens to add with 5 ones so that we can have 15 ones in place of 5 ones. As a result, 3 tens in place of 4 tens.


Step 2:
$\because 1\text{hundred}=10\text{tens}$
In number 645, We will borrow one hundred(or 10 tens) from 6 hundreds to add with 3 tens so that we can have 13 tens in place of 3 tens. As a result, 5 hundreds in place of 6 hundreds.
