Find the following: 800 take away
In this question, we’re subtracting
a three-digit number from a three-digit number. And when we’re using the standard
written method, we always start by subtracting in the ones column. But we have a problem because 800
has no ones, and we need to subtract two. And we have another problem. There are no tens in the tens
column, so we need to move to the hundreds digit to help us regroup. We need to take one of our hundreds
and exchange it for 10 10s. And now we need to take one of our
tens and exchange it for 10 ones.
Now we can start to subtract in the
ones column. 10 take away two is eight. Next, we can subtract in the tens
column. We’ve got nine 10s, and we need to
take away six, which leaves us with three 10s. And finally, we can subtract the
hundreds. Seven 100s take away five 100s
leaves us with two 100s. 800 subtract 562 equals 238.
