regrouping in subtraction?

Question

explain how you regroup in subtracting 153 from 224.. which is correct? take 100 from hundreds so that i have 12-5 or take 1 from hundreds to have 12 - 5?
1 or 100?

Answer 1

Borrow a 1 from the 100s column. That's also 10 tens, so your 2 tens becomes 12 tens. Then you can subtract 5 tens from 12 tens

When I learned this back in the stone age, I'm 53, we called it 'borrow' that's what you're doing. You borrow a 100 and use it as 10 tens.

When you multiply then it's a 'carry' to the next column.

This is the real beauty of the place value number system.

Answer 2

subtracting 153 from 224 will be written as 224-153
first the three in the units place of153 will be subtracted from the 4 in the units place of 224 and then you move to the tens place and lastly the hundreds place in this case.
1 12 4
1 5 3
--------
0 7 1
