Necessary Mathematics Symbols You Need For 2013/14 WAEC GCE Mathematics Answers / means DIVISION * means multiplication tita u should know dat. rais means raise to power ^ means raise to power sqr rut/ squar rut means square root ----(1) means equation 1 yr means year f(x-xbar) means x MINUS x BAR as in statistics which means that MINUS WILL BE ON TOP OF x. ,(Comma) means NEXT LINE, THIS MEANS THAT THE FOLLOWING NUMBER IS UNDER THE NUMBER IT IS FOLLOWING i.e UNDER. It is usually used during STATISTICS when drawing a table. EXAMPLE 1. X;1,2,3,4, FX; 4,6,8,10 FX-Xbar; 10,8,6,4, DRAW A TABLE WITH X|FX|(FX- Xbar) The above statement means that; ~For X, it has 1 2 3 4 5 6 under it. which means 1 is under 2, 2 is under 1, 3 is under 2, 4 is under 3 and so on... ~Under FX you have 4, then 6 under 4, then 8 under 6, then 10 under 8, then 12 under 10..... ~Under FX-Xbar you have 10, then 8 under 10, then 6 under 8, then 4 under 6, then 2 under 4, then 1 under 2.... IN A CLEARER WAY:- → comma means NEXT LINE(e.g) x ; 1,2,3 fx ; 4,5,6 fx-xbar ; 10,8,6,4 x|fx |fx-x¯¯| 1| 4 | 10 | 2| 6 | 8 | 3| 8 | 6 | 4| 10| 4 | ANOTHER EXAMPLE; Class interval; 60-64,65-69,70-74,75-79,80-84,85-89,90-94,95-99. X; 62,67,72,77,82,87,92,97. F; 2,3,6,11,8,7,2,1. FX; 124,201,432,847,656,609,184,97. F(x-x bar)2; 561.12,414.18,273.36,33.66,84.48,476.42,351.12,333.0 MEANING OF THE ABOVE EXPRESSION:- Bar means Minus on top of d number or Variable and comma means next line which means each of them are unda. Eg 60-64 is unda Class interval, then 65-69 is unda 60-64,etc .So comma means unda. NOTE THAT WHEN U SEE SOMETHING LIKE THE ABOVE TWO EXAMPLES, U WILL NEED TO DRAW A TABLE.. YOU NEED TO KNOW THESE ALSO; MATHS CODES:- 1) ,(comma) means next line. (e.g) x ; 1,2,3 fx ; 4,5,6 fx-xbar ; 7,8,9 x|fx |x¯¯| 1| 4 | 7 | 2| 5 | 8 | 3| 6 | 9 | 2)*=multiplication sign. 3)^ = Riase to pwer 4)P also means raised to power eg 10P6 means 10 raised to power six. 5)log3(base4) 4) ..Note:- the base must be SUB. 6)x bar = mean symbol(x¯¯) 7)Pie = pie symbol eg Area of a circle is (Pie r2). Tita = θ eg Sinθ. 9)Root or Rut or Sqrt or sqr root = √ ; eg Root2 means √2 10)/ means ÷ 11)----(1) means equation 1 NOTE:- "CLUE FOR GCE MATHEMATICS EXPOSED.
