Problem Solving.

 I learnt how to problem solve.

First I read the question to find the mathmatical equation. It is 32-13.

Next we solved the answer for counting back. We subtracted 10 from 32 which is 22 then we counted back from 22 until we got the answer. 

Then we solved the anwser to splitting. We wrote 32-10=22 then we wrote 22-3=19.

Finally we solved the answer to rounding and compensating. We wrote 30-13=17 then 17+2=19 then 32-13=19.

I enjoyed this because if my job is a cashier I need to learn easy stratergy.\
