Twenty taking away facts that start from a teen number, such as 14 − 6 or 17 − 4. Half of them cross back through ten, where children go back to ten first and then take away the rest: 14 − 6 is 14 − 4 − 2. The other half stay in the teens or take away ten. Each answer is written in a heart, and none is below 1.
