OBJECTIVES Development of an easy mathematical

approach towards the students. To know in the better way the terms used

in mathematic in English. Using these symbols and signs we are able

to understand international books about Mathematics without knowing their language( i.e. Chinese and Japanese).

It is the better way to create the attention towards the subject.

MATHEMATICS

Science (or group of related sciences) dealing with the logic of quantity and shape and

arrangement)

The study of the measurement, properties, and relationships of quantities and sets, using numbers

and symbols.

Symbol: +

What is it: Addition sign

How is it read: Plus

How it is used : Sum of a few values

Expression sample: t3 + 2 = 5

APPROXIMATE SIGN

~ Approximate

equal sign is approximately equal to Indicates two values areclose to each other

x + y ~z

SUMMATION

EQUALITY SIGN

= Equal sign shows that two

quantities are equals Indicates two values

are the same -(-5) = 5

2z + 4z – 6Z = 0 =

=

INEQUALITY SIGN Inequality sign is

not equal to Indicates two valuesare different

x≠ y

≠

GREATER THAN > > Inequality sign is

greater than Indicates value on

leftis larger thanvalue on right

5 > 3x > y

GREATER OR EQUALITY SIGN ≥

Inequality sign is greater than or equal to. Indicates value on left is larger

than or equal to value on right side.

x ≥y

LESS THAN < Inequality sign is less than . Indicates value on left side is less than value on right

side. x <y

3 < 5

<

LESS OR EQUALITY SIGN

≤ Inequality sign is less than or equal to is

at most equal to Indicates value on left

side is smaller than or equal to value on right side.

X ≤ y
