* means Multiplication

tita You Should Know that.

rais means Raise to power or

^ means Raise to power

sqr rut or square rut means Square root

yr means Year

f(x-xbar) means x MINUS x BAR as in statistics

which means that MINUS will be on Top of x.

, (Comma3) means NEXT LINE,

**MORE UNDERSTANDING BELOW**

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) ^ = Raise to power

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 = means symbol (x¯¯)

7) Pie = pie symbol e.g Area of a circle is (Pie r2).

8) Tita = θ e.g Sinθ.

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

10) / means ÷

11) —-(1) means equation 1

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 under.

Eg 60-64 is unda Class interval,

then 65-69 is unda 60-64,etc .So comma means under.

**NOTE:** When you see something like the above example two, you will have to draw a table.

The Image Above Is A Logarithm. This symbols we will use to represent it below…

No:92.63, Log:1.9667

No: 2.914, Log: 0.4645

2.4312

Antilog = 269.9

Therefore 92.63*2.914=2.4312
