The language of your Maths exam! Don’t work out exactly! Round the numbers, then tell the answer. Estimate Estimate 4.7 x 6.2 Answer: 5 x 6 = 30 Simplify Collect like terms together Simplify e + 7e Answer: 8e Work out A written or mental calculation is needed. Work out 62 Answer: 6 x 6 = 36 Calculate You will need to do a sum either with or without your calculator. You must show your working If you don’t show your working you won’t get ALL the marks! Give your answer in its simplest form Cancelling of a fraction or ratio is needed. 12 : 15 simplified is 4 : 5 Explain You must state why! Expand Multiply out (remove brackets) Expand 4 ( 3x – 2) Answer: 12x - 8 Factorise To find factors (put brackets in) Factorise 6x + 10x2 Answer: 2x( 3 + 5x) Solve Find the value of, usually find what x is! Solve: 3x = 12 Answer: x = 4 Describe fully Usually transformations: Translation by a vector (2 marks) Enlargement of a scale factor about a point (3 marks) Reflection in a mirror line (2 marks) Rotation through an angle about a point (3 marks) Measure Use a ruler or protractor to accurately measure lines or angles. Construct, using ruler and compasses Your ruler is a straight edge and compasses must be used to draw arcs. Sketch An accurate drawing is not needed; freehand will do! Diagram NOT accurately drawn Don’t measure angles or sides.
