Find the following: 900 subtract
533 equals what.
In this question, we have to use
the standard written method to subtract 533 from 900. We could model 900 using our place
value chart. The only digit in 900 which has any
value is the hundreds digit. 900 has nine 100s, no tens, and no
ones. So before we can subtract in the
tens column and the ones column, we’re going to need to regroup. We can start by taking one of our
hundreds and exchanging it for 10 10s. But we still don’t have any ones to
subtract our three from. So we’re going to need to take one
of our tens and exchange it for 10 ones.
Now we have enough ones. Let’s start subtracting. 10 ones take away three ones leaves
us with seven ones. Nine 10s take away three 10s leaves
us with six 10s. And eight 100s take away five 100s
leaves us with three 100s. 900 subtract 533 is 367.
