Maths problem sets in calculus, linear algebra and discrete maths come back typed, one step per line, with a short note wherever a step is not obvious. Science lab reports in physics, chemistry and biology follow the structure your course sets, usually aim, hypothesis, method, results, analysis, discussion of error and conclusion, built from your own readings.
For discrete maths, our Boolean algebra worked example shows the format: the laws in one table, how to build a truth table, then Karnaugh map simplification and solved questions. In a lab report, the discussion explains why the measured value differs from the expected one and separates random from systematic error. A lab report for an engineering module, with design calculations or a department template, belongs with our engineering lab reports.
