### How do you write the number 3 tens and ones less than 67?

3 tens is equal to the number 30, and 3 ones is equal to the
number 3.
So, 3 tens and 3 ones is 33; and 67 minus 33 (or 67 less
33) is 34.
You could also look at the number 67 and see that it is 6 tens
and 7 ones. Then it is easier to say "6 tens and 7 ones minus 3
tens and 3 ones = 34"
because:
6 tens minus 3 tens = 3 tens, and 7 ones minus 3 ones =
four ones.
3 tens and four ones = 34
