Example Question #22 : How To Subtract Integers
Subtract:
Subtract the ones digits.
Because the tens digit of is less than the tens digit of
, we cannot subtract the tens digit. We need to borrow a one from the hundreds digit of
. The hundreds place becomes a zero.
Subtract:
The answer is:
Example Question #22 : How To Subtract Integers
Subtract:
The ones digits cannot be subtracted unless one is borrowed from the tens digt.
This becomes:
This is the ones digit of the final answer.
The tens digit of becomes a
. We also cannot subtract a
with the
in
, which means we will need to borrow a one form the hundreds digit of
, which will become
.
Subtract:
This is the tens digit of the final answer.
Subtract the new hundreds digits.
This is the hundreds digit.
The answer is:
