Predict: I predict that this question will be about addition.
Read: Fill in the magic square. [Hint: Every row, column and diagonal has the same sum.
Clarify: I had nothing to clarify in this question.
Mathematician’s Toolbox: The strategy I used from the mathematician’s toolbox was prior knowledge.
Big question: The big question is what are the missing numbers in the magic square.
Solve: Firstly, I worked out that all the numbers that were in a row made 18, and those numbers were 8, 6 and 4. Next to the 8 there was 7, so I added 3 to make 18. After that, it was easy going because I knew basic addition.
Summary: This problem was quite easy to solve if you knew basic addition of numbers.
