Predict: I predict I will have to use Roman numerals.

Read: Move one match to make this statement correct. V+I=V

Clarify: Nothing to clarify.

Mathematicians Toolbox Strategy: Make a number sentence.

Solve: first I worked out what the numbers were. They are 5+1=5. I saw a number problem like that I could do 6-1=5.

First I moved the vertical line from the + to the first 5 I put it in front of the V. Then I got this IV-I=V. That my answer.

Summery: It was easy because I know most of the Roman numerals.
