To those of you that have already subscribed for the Maths & those who will still subscribe, Here are the Mathematics Symbols we make use in all our 0’level Exams such as WAEC, NECO, NABTEB AND GCE EXAMS Maths Assistance Program.

/ 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.
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 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
