Math Symbols  Greater
Than & Less Than
The greater than > and less
than < symbols are familiar to everyone! The two signs are used to show
inequality between two numbers. Inequality is defined as an expression
which consists of two unequal quantities, with the sign of inequality (>
or <) between them; as, the inequality 1 < 2, or 5 > 2. Other symbols
used for greater and less than are shown in the table below:

Math Symbols  Solving
Problems
Symbols are a vital part of
solving math problems and although it is impossible to remember every
math symbol, it is important that we are familiar with the symbols used
in everyday life. Math symbols are taught to children all over the
world, they are a global language regardless of the language spoken.
Math Symbols  Roman
Numerals
The Romans used letters from
the Latin alphabet for their numeric system. Although an ancient system,
Roman numerals are still occasionally used today. Movie credits often
use Roman numerals to display the year that the film was made e.g. the
year 2013 is displayed as MMXIII (2 x M to represent 1000, 1 x X to represent 10 and
3 x III to represent the number 3). The names of monarchs and popes also
use Roman numerals, e.g. Queen Elizabeth II and Pope Francis I.
Occasionally Roman numerals are featured on clock faces instead of
numbers.

Statistical Math Symbols
Statistics is defined as the
branch of applied math which is concerned with the collection and
interpretation of quantitative data and the use of probability theory to
estimate population parameters. Common terms encountered in statistics
are Mean, Median and Mode.
Math Symbols  Geometry
Geometry is defined as being
the branch of math which investigates the relations, properties,
and measurement of solids, surfaces, lines, and angles; the science
which treats of the properties and relations of magnitudes; the science
of
the relations of space. Common math geometry symbols include:

Greek Math Symbols
The Greek mathematician
Pythagoras is described by many as being the first pure mathematician
and is famous for his quote "Numbers rule all things". Pythagoras
considered the number five to be the symbol of humanity and the number
ten represents diving power. Pythagoras is most famous for his theorem
which states that in any rightangled triangle, the area of the square
whose side is the hypotenuse (side which is opposite the right angle) is
equal to the sum of the areas of the squares whose sides are the two
legs (two sides that meet at a right angle). His theorem can be written
as an equation which relates to the lengths of the sides a, b and c, and
is also called the the Pythagorean equation: a^{2
+ }
b^{2
}
= c^{2 }
where c represents the length of the hypotenuse and a and
b represent the lengths of the other two sides.
Math Symbols  Formula
A mathematics formula
can be defined as a rule or principle which are expressed in algebraic
language. A formula is a prescribed or set form; an established rule; a
fixed or conventional method in which anything is to be done, arranged,
or said. In computing terms, a formula is defined as a logical sequence
of symbols which representing terms, predicates, connectives and
quantifiers which are either true or false.
Math Symbols  Equations
An equation is an expression
of the condition of equality between two algebraic quantities or sets of
quantities in math, the sign = is placed between them. Examples include binomial
equations; quadratic equations, algebraic equations, transcendental
equations, exponential equations, logarithmic equations or differential
equations.

Symbols
Fact 1: Our math counting system is called Base10 as we
use the numerals 0 to 9 and then reuse the digits when
we reach the number 10 

Math Symbols
Fact 2: Computers use the Base2 counting system,
also known as binary. Base2 uses the numbers 0 and 1,
computers store data using a switching system, the
number 1 is used to indicate on and 0 is used to
represent off 

Math Symbols
Fact 3: On a computer numbers can be coded as
magnetic charges, using the binary system of 0 and 1,
either there is a charge or no charge, data is stored to
magnetic disks in this way 

Math Symbols
Fact 4: The hexadecimal (Base16) number format is
used by computers for higher level functions, the
numbers 09 are used as well as the characters AF 

Math Symbols
Fact 5: The term Infinity is often used in
mathematics and it is defined as something without a
limit. The infinity symbol ∞ was introduced by the
English mathematician John Wallis and it is sometimes
referred to as the 'lazy 8' 

Math Symbols
Fact 6: A mathematical genius is referred to as a
'savant'. A savant is defined as someone with
outstanding ability and mathematical savants have the
ability to remember complex number sequences and solve
difficult calculations without the need for a calculator 

Math Symbols
Fact 7: The German mathematician Carl
Gauss(17771855) was known by the Latin term 'Princeps
mathematicorum' meaning 'Prince of Mathematics' due to
his amazing ability and his contribution to the world of
mathematics 

Math Symbols
Fact 8: A quintillion is the number one followed by
18 zeros and a Septillion is the number one followed by
24 zero's! 

Math Symbols
Fact 9: A maze with a single route through it is
called a unicursal maze. The Cretan maze (over 3,200
years old) is an example of a unicursal maze 

Math Symbols
Fact 10: The prefix 'milli' means a thousand 

Math Symbols
Fact 11: The prefix of the smallest possible unit is
a 'yocto' and a yoctometre is 1 / 10^{24
}of a metre 

Math Symbols
Fact 12: The prefix 'centi' means one hundred 

Math Symbols
Fact 13: The number 1 followed by 100 zeros is
called a googol! The term was invented by Milton Sirotta
who was the nephew of mathematician Edward Kasner in
1938 

Math Symbols
Fact 14: Shapes that fit together without gaps are
referred to as 'tessellating', mozaics are examples of
shapes that 'tessellate' 

Math Symbols
Fact 15: Complicated patterns that continue no
matter how small the shape gets is called a 'fractal'. A
real snowflake is an example of a fractal!
