Teaching guide
Use mathematical modelling with linear, quadratic or exponential models to solve growth and decay problems, then evaluate and report on the model.
Build algebra from arithmetic: use a variable to stand for an unknown, write the situation as an expression or equation, then keep both sides balanced when solving and check by substituting the answer back in.
Generated and checked in code, so it is correct.
Treating the equals sign as 'work it out' rather than 'both sides are equal', dropping negative signs, and not applying an operation to every term.
