The students will gain better understanding of what each component of an expression does in practice in maths and how it can be applied to other calculations. This scenario also contributes to teaching programming and algorithmic thinking.

Debugging the mathematic formula open by counting.
Run through each part of the generated expression as a debugger while solving the equation. The formula is applied and the calculation is run through line by line like a code would be.
This method can also be used to check an already solved calculation. If there is an error in the calculation, a ‘break point’ is made at the point where the error occurred.
Notes should be written on a separate debugging sheet or on another page of the notebook.
Students should work in pairs to check each other’s calculations at the end of the lesson.
