Subtraction involving ones and tens

Solve the following problems.  Write down the steps you took to solve them.  Share your work with a buddy ask them to give you feedback using the comments.
Faith had 45 rabbits and 21 got eaten by a bear.  How many rabbits does she have left?
40-20=20
then 5-1=4 so you add the 1en and ones so it is 24.

Falakiko won 52 lollies in a running competition.  He gave away 21, how many does he have left?
50-20=30

so 2-1=1 so it is 31
