Teaching guide
Recognise how using approximations of real numbers in repeated calculations affects the result compared with exact values.
Compare a chain of calculations done with rounded values against one done with exact values, and see how small approximations build up across repeated steps.
Generated and checked in code, so it is correct.
Rounding too early in a multi-step calculation, which grows the error in the final answer.
