XCITYNIGERIA MATHEMATICS SYMBOL CLASS TUTOR

THIS IS HOW WE WILL PRESENT OUR MATHS ANSWER

YOU CAN ASK QUESTIONS IF U ARE CONFUSED WITH
ANY SYMBOL.

/ 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,

FX- 4,6,8,10

FX-Xbar- 10,8,6,4,

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....

IN A CLEARER WAY-
→ comma means NEXT LINE(e.g)

x - 1,2,3

fx - 4,5,6

fx-xbar - 10,8,6,4

x|fx |fx-x¯¯|
1| 4 | 10 |
2| 6 | 8 |
3| 8 | 6 |
4| 10| 4 |

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..

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 eg 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 eg Area of a circle is (Pie r2).

8Tita = θ eg Sinθ.

10)Root or Rut or Sqrt or sqr root = √ ; eg
Root2 means √2

11) / means ÷

12)----(1) means equation 1
