/ means DIVISION
* means Multiplication
tita You Should Know that.
rais means Raise to power or
^ means Raise to power
sqr rut/square 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
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.
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. When you see something like the above example two,
you will have to draw a table.

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 e.g 10P6 means 10 raised to
power six.
5)log3(base 4) ..Note: the base must be SUBSCRIPT.
6)x bar = mean symbol(x¯¯)
7)Pie = pie symbol e.g Area of a circle is (Pie r2).
8)Tita = θ e.g Sinθ.
10)Root or Rut or Sqrt or sqr root = √ ; eg Root2 means √2
11)/ means ÷
12)—-(1) means equation 1
