26 Percentage means fraction out of % = 0.5 = ½... divide by 2 25% = 0.25 = ¼... halve then halve again 10% = 0.1 = 1 /10... divide by 10 1% = 0.01 = 1 / divide by 100 To calculate a percentage increase (or decrease), find the percentage and add it on (or take it away) Eg to increase 120m by 15% 10% of 120m = 12m 5% of 120m = 6m 15% of 120m = = 18m 120m + 18m = 138m Negative Numbers Replace - - with + eg 3 (-4) = = 7 Replace + - with - eg 3 + (-4) = 3-4 = = + eg 3 4 = = = - eg (-3) 4 = = = - eg 3 (-4) = = = + eg (-3) (-4) = = + Fractions of To find a fraction of an amount you divide by the bottom and times by the top Eg to find 2/3 of 18m you do 18 3=6 then 6x2=12m BRACKETS INDICES DIVISION MULTIPLICATION ADDITION SUBTRACTION Laws of Indices a b a b y y y Perform calculations in the correct order Adding and Subtracting Fractions Make sure the fractions have a common denominator before you add/subtract them eg a y a b a b ( y ) y y 0 1 b y y = mx + c (equation of a straight line) m = gradient c = y-intercept gradient (steepness) = change in y change in x y a b Types of Number odd ends in 1, 3, 5, 7, 9 even ends in 0, 2, 4, 6, 8 (is divisible by 2) factor divides exactly into a number eg 5 is a factor of 10 multiple in the times table of a number eg 20 is a multiple of 10 prime number - can only be divided by one and itself: 2, 3, 5, 7, 11, 13, 17, are prime Highest Common Factor (HCF) of 2 numbers the largest value that divides exactly into both numbers Lowest Common Multiple (LCM) of 2 numbers the smallest value that is in the times tables of both numbers nth terms First find out how you get from term to term this tells you the times table the sequence is based on eg 4, 7, 10, 13,... goes up in 3s so the sequence is based on the 3x table (3n) Then find out what you need to add or subtract from this times table to get the required sequence. eg 4, 7, 10, 13,... is one more than the 3x table so the nth term is 3n + 1 To plot straight lines you can use triangle numbers etc a table of values the cover-up method y-intercept and gradient Check the scale carefully. square numbers 1 2 =1 2 2 =4 3 2 =9 4 2 = = = = = = = = = = = =225 Product of Prime Factors = = (index form) square roots cube numbers 1 3 =1 2 3 =8 3 3 = = = = cube roots

Metric Conversions: 1cm = 10mm 1m = 100cm 1m = 1000mm 1km = 1000m 1kg = 1000g 1tonne = 1000kg 1 litre = 1000ml 1 litre = 100cl Names of shapes: square still a square! rectangle Imperial to metric rough conversions: 5 miles = 8 km 1kg = 2.2 pounds 1 gallon = 4.5 litres Key formulae: Circumference of circle = πd Area of rectangle = length x width Area of triangle = base x height 2 Area of circle = πr 2 Volume of cuboid = length x width x height Volume of prism =cross-section area x length perimeter is the distance round the edge area is the space inside the shape rhombus parallelogram kite trapezium cuboid cone cylinder triangular prism square-based pyramid triangle-based pyramid (tetrahedron) Angle Rules: Opposite angles are equal Angles on a straight line add up to 180 Angles at a point add up to 360 Angles in a triangle add up to 180 right angle Angles in a quadrilateral add up to 360 Alternate angles in parallel lines (Z angles) are equal Corresponding angles in parallel lines (F angles) are equal Interior angles in parallel lines (C angles) add up to 180 acute obtuse reflex Quadratic Graphs Distance, Speed, Time Pythagoras theorem y = ax 2 +bx+c S D x T a c a 2 + b 2 = c 2 (c is the hypotenuse the longest side) b
