How to form and solve the nᵗʰ terms of linear and quadratic sequences.

Linear equations are equations that, when plotted on a line graph, produce a straight line.

Algebraic expressions are collections of numbers, letters and symbols. They are evaluated by replacing their variables with numerical values and turning them into equations.

Normal rounding is quite simple, significant figures is a more advanced form. Estimation is using both methods to produce a rough answer to a problem.

Look at the bloody title.

There are three types - mean, mode and median. Also sort of range...
