MATHEMATICAL SYMBOLS

thank you for reading

In every mathematics calculation one must use mathematical symbols to get a result, symbols show the relationship or operations between two numbers or integers.

LIST OF MATHEMATICS SYMBOLS

1. Addition +

this adds two numbers together to give a SUM

e.g 3+4= 7, 4+5=9, 2+2= 4, 6+4= 10 etc.

2. Substraction -

subtraction shows the difference between two numbers

example: 4 - 2 = 2, 3 - 1 = 2 , 6 - 4 =2, 8 - 6 = 2, 10 - 8 = 2, etc

in the example above, the difference between each number is 2.

3. Multiplication *

this mathematical symbol gives the product of two numbers.

example: 3 * 4 = 12, 12 * 1 = 12, 5 * 5 = 25, 3 * 2 = 6, etc

4. Division /

As you know, when this symbol is between two numbers it means to divide one number by another a quotient.

example: 4/2 = 2, 6/2 = 3, 8/ 2 = 4, 10/2 = 5, 20/2 = 10, etc.

5. less that (<) and greater than (>)

this symbol looks like the heads of two arrow moving in opposit directions. the less than symbol means that a number is lower less than another number, example.

2 < 5, 3 < 5, 4 < 7, 5 < 8, 9 < 12 , etc.

and the greater than symbol means one number is greater than another number, example.

4 > 2, 6 > 4, 5 > 2, 7 > 4, 11 > 6, etc.

6. Equals =

As you can see this Mathematical symbol was used to show the result of the sum, difference and product of two numbers. it's also used to show when one number is equal to two numbers.

example:

2 = 1 + 1, 3 = 2 + 1, 4 = 2 + 2, 6 = 3 + 3, 10 = 5 + 5, etc.

there are a lot of mathematical symbols, i'll discuss them later, but for now this are the basics.

　

Numbers

Modern mathematics numbers are based on 10. at the end of every successive 10 the number changes. example:

         0,  1,2,3,4,5,6,7,8,9,10 at 10 the next number increases by 1 to the right the number is 11, the number to the left remains the same indicating the base of 10 and any number to the right is an addition to 10.

let me explain it using money the mathematical numbers are based on $10. at the end of every successive $10 the number to the left changes. example: 

                     $0,  $1, $2, $3, $4, $5, $6, $7, $8, $9, $10, if someone adds $1  to  $10 it will be $11.

 this are the basic mathematical numbers.

A BRIEF HISTORY OF MATHEMATICS

The word Mathematics was made by the followers of a Greek mathematician-Pythagoras. the word was made from a Greek word mathema which means " Something learned".

Mathematics had a remarkable history. Ancient Mathematics involved simple counting. During the Agrarian Age, people used simple counting to number their livestock and any other thing but, as time passed other Empires invented more Mathematics ideas.

Ancient Empires like the Babylonians, Egyptians, Greece, China and Indian's invented different mathematical ideas and principles that are still used today.

Egyptians used Arithmetic and Geometry to solve problems. Arithmetic is the basic math idea of addition, subtraction, multiplication and division ( the symbols; Addition +. Subtraction -, Multiplication *, and division    /). Geometry relates to mathematical shapes, angles, curves, lines, points, solids and surfaces. Also, Ancient Egyptians based their number system on 10 that's why modern  number system is based on 1, 10, 100, 1,000, 10, 000 etc.

Ancient Babylonians also used Arithmetic, Algebra and Geometry. A very prominent Babylonia Mathematics idea was the Sexagesima numeral system that was based on the number 60 this, they used to divide the minute into 60 seconds, an hour into 60 minutes and the day into 24 hours of 60 minutes, for each hour. The Babylonians also had different methods to solve linear and quadratic equations.

Ancient Greek's founded their mathematics on Babylonian and Egyptian Mathematics idea's. this is what the Encarta Encyclopedia says,
    " The Greeks adopted elements of mathematics from the Babylonia and Egyptians. The new element in Greek Mathematics was the invention of an abstract mathematics founded on a logical structure of definitions, axion ( propositions accepted as self-evident) and proofs".

Many believe that Thales of Miletus made the start of Greek Mathematics. Many Greek Mathematicians made notable contributions, such mathematicians include: Thales of Miletus, Pythagoras, Plato, Eudoxus of Cindus, Aristotle, Musaeum of Alexandria, Euclid, Hypatia of Alexandria, Archimedes and many more remarkable individuals.

this just a very brief history of mathematics, a more comprehensive article will be provided later.
