(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) ^ = Raise to power 4) P also means raised to power e.g 10P6 means 10 raised to power six. 5) log3(base 4) ..Note: the base must be SUBSCRIPT. 6) x bar = means symbol (x¯¯) 7) Pie = pie symbol e.g Area of a circle is (Pie r2). 8) Tita = θ e.g Sinθ. 9) Root or Rut or Sqrt or sqr root = √ ; eg Root2 means √2 10) / means ÷ 11) —-(1) means equation 1 This means that The Following Number is Under The Number its Following ie. UNDER. It is usually used during STATISTICS when drawing a table. EXAMPLE 1 X: 1,2,3,4,5,6 FX: 4,6,8,10,12 FX-Xbar: 10,8,6,4,2,1 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. EXAMPLE 2: Class interval: 60-64, 65-69, 70-74, 75-79, 80-84, 85-89, 90-94, 9 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. mathematics symbl waec neco nabteb gce 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 under. Eg 60-64 is unda Class interval, then 65-69 is unda 60-64,etc .So comma means under. NOTE: When you see something like the above example two, you will have to draw a table.
