3 Digit Subtraction with Regrouping – Question 1
Subtract the following:
Explanation
If we want to Subtract the digits at ones place, we have
3 – 4
But 4 is greater than 3
We would need to borrow 1 from 5 in tens place
3 in ones place would now become 13 and 5 in tens place would be reduced to 4
So, 13 – 4 = 9
Subtracting the digits at tens place
4 – 4 = 0
Subtracting the digits at hundreds place
6 – 3 = 3
Hence, the difference is 309
3 Digit Subtraction with Regrouping – Question 2
Subtract the following:
Explanation
If we want to Subtract the digits at ones place, we have
3 – 9
But 9 is greater than 3
We would need to borrow 1 from 5 in tens place
3 in ones place would now become 13 and 5 in tens place would be reduced to 4
So, 13 – 9 = 4
If we want to Subtract the digits at tens place, we have
4 – 7
But 7 is greater than 4
We would need to borrow 1 from 8 in hundreds place
4 in tens place would now become 14 and 8 in hundreds place would be reduced to 7
So, 14 – 7 = 7
Subtracting the digits at hundreds place
7 – 1 = 6
Hence, the difference is 674
