14 1848 – 1400


448


– 420 28


– 28 0


Now we can get an answer in the tens column by estimating how many times 14 goes into 44.


14 × 3 = 42, so we can put 3 in the tens column. This is really 14 × 30 = 420, so we subtract 420.


Now we can get an answer in the units column by estimating how many times 14 goes into 28. 14 × 2 = 28, so 2 is the answer in the units column and there is no remainder.


So he collected 132 hats every year.
