Estimating

When GCSE questions ask you to estimate the result of a numerical calculation on the non-calculator paper you should proceed as follows:

Round the numbers in the problem to 1 significant figure before performing calculations.

Be careful if you have a number less than 1 for a denominator. For example, if the denominator = 0.4 then multiply the numerator and denominator by 10 so that you end up dividing by the whole number 4.

Use of Calculator

When asked to use your calculator to evaluate an expression, use brackets to group terms in a numerator, terms in a denominator, and terms under a square root sign. Leaving out brackets risks the order of precedence rules on your calculator causing it to evaluate calculations in an inappropriate order for the question.
