Predict: I predict this will be about finding the original number.

Read: I think of a number, divide it by 2 and then add twelve. If the result is 20, what was the original number?

Clarify: I had nothing to clarify

Big question: What was the original number?

Tool: I used work backwards

Solve: First, I took away 12 because I was working backwards. That was 8. I would then multiply that by 2 and that gave me the answer of 16.
