GEmdas REMINDER! If only two of the operations are being used it has to be left right like addition to subtraction or multiplication to Division. BUT if its like addition and Multiplication……and all follow the GEMDAS rule where its groupings, then exponent multiplication, Division addition then subtraction Example: 134 + 73 – 66 = 142 560 + 10 / 5 = 562 857 x 12 / 6 = 1714 (25 + 10 – 5 ) -10 = 20 (55 / 5 x 10 ) x 2 = 220 Exponents - They are the small numbers on top a number that tells you how many times you multiply a number to itself 3 5 4 = 5 x 5 x 5 = 125 6 = 6 x 6 x 6 x 6 = 1296 12 2 = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 4096 Fractions - NOT BIGGER THAN A WHOLE Kinds of Fractions Proper Fraction The Numerator is NOT bigger than the Denominator Ex: 3/5 5/7 12/120 Improper Fractions The Numerator is MORE than the Denominator Ex: 7/5 6/2 19/10 Mixed Fraction A Fraction Where there is a whole no. Ex: 1 2/3 5 3/4 Unit Fraction A Fraction that the numerator is 1 Ex: 1/12 ¼ ½ 1/5 Operations Addition You have to find the LCD of BOTH the fraction then multiply the numerator with how much times you CHANGED it… Ex: ¾ + ½ =? Then… 4= 4 8 12 16…. 2= 2 4 6 8 20…… 3x2 & LCD is 8 1x4 =6& 4 6/8 + 4/8 = 10/8 = 5/4 = 1 ¼ Subtraction Same as addition you have to find the LCD of both fractions and multiply the numerator with how much times you CHANGED it ¾ - ½ = ? LCD is 8 Then… 3x2 & 6/8 – 4/8 = 2/8 = 1/4 1x4 =6& 4 Multiplication Just Multiply Numerator to Numerator and Denominator to Denominator Ex: 2/5 x 2/4 =? 2x2=4 5 x 4 = 20 4/20 = 1/5 Division Find The reciprocal of the Divisor then Multiply the rest… Ex: 2/5 / 4/5 = ? 2/5 x 5/4 = ? 2 x 5 & 5 x 4 = 10 & 20 = 10/20 = ½ Surface areA - Sum Of ALL sides of the Shape FORMULAS Cube: side x side x 6 Rectangular Prism: Length x 2 + width x 2 + height x 2 2 Cylinder: 2 pi r + 2 pi r h Volume - The Space Inside a 3 Dimension Figure TIP! 1 way to find the volume of a prism is… Area of the base x Height FORMULAS 3 Cube: S x S x S = S Cuboids: L x W x H 2 Cylinder: pi x r x h Triangular Prism: ½ x b x h x l Rules of exponents Multiplying If the no. you are multiplying have the same bases then just add the exponents.. 5.5.5.5.5.5.5 12 ________ = 5 5.5.5.5.5 Division the same goes with dividing but this time instead of adding the exponents you Subtract 6.6.6.6.6.6.6.6 3 _________ = 6 6.6.6.6.6 0 TIP! Anything to the power of zero ( 4 ) is equivalent to 1! And cancelation is Possible Love Your Beautiful VP
