MATHEMATICAL SYMBOLS:
These are some Symbol that We're going to be Using In solving Today's Mathematics Examination.
1) ,(comma) means next line.
2) *=multiplication sign.
3) figures after any alphabet or closed bracket means superscript or raised to power eg
(i) 4x3 means 4x raised to power 3.
(ii) (2x+y)2 means (2x+y) raised to power two.
4)P also means raised to power eg 10P6 means 10 raised to power six.
5)log3(base 4) ..
Note:the base must be SUBSCRIPT .
6)x bar = mean symbol
7) Pie = pie symbol eg Area of a circle is (Pier2).
8 ) Tita = angle symbol eg Sin(tita).
→ / means ÷
→ * means X
→ tita means θ
→ rais means x4
→ ^ means Raise to Power
eg: 2^4 means TWO raise to power 4.
→ cube rut e.g 3√27
→ squar root means √
→ ----(1) means equation 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 |
or this
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:1,2,3,4,5,6
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....
