What children learn in Level 14

To subtract 58,764 minus 23,512, line up the places and take away each one.
Ones: 4 minus 2 is 2. Tens: 6 minus 1 is 5. Hundreds: 7 minus 5 is 2. Thousands: 8 minus 3 is 5. Ten thousands: 5 minus 2 is 3.
When a place doesn't have enough, break 1 from the place to its left. In 6,245 minus 1,380, there are only 2 hundreds, so break a thousand into 10 hundreds: now there are 12.
12 hundreds minus 3 hundreds is 9 hundreds, and 5 thousands minus 1 thousand is 4 thousands. 6,245 minus 1,380 is 4,865.
