Students explore regrouping to solve addition problems involving
carrying. They learn to subtract from the top ones enough to
make ten with the bottom ones and the difference is placed below
the equal line in the ones column. Then the subtracted amount
is added to the bottom ones to make ten. A small one representing 
the ten is placed below the equal line to the left of the ones. 
This one is added to the tens above and the sum placed below
the equal line in the tens column.
