# WAEC/NECO MATHEMATICS/PHYSICS SYMBOLS

Below are the Maths Symbols you will see in Our Solutions Tomorrow,

So u need to study them very well.

/ 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:1,2,3,4,5,6

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….

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:

561.12,414.18,273.36,33.66,84.48,476.42,351.12,333.06

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..

I WILL UPDATE MORE LATER.
