### Mathematical contributions of Fibonacci

Fibonacci introduced the arithmetic system of Hindu-Arabic fundamentals in Europe for the very first time. Its still the positional systems which are continued to be used till today. It contains ten digits and zero and a decimal point.

Fibonacci had written a book - Liber abbaci, the book on abacus or calculating, which explains the different logical methods for doing the arithmetic in the logical and decimal system. This book was completed by 1202 and simultaneously Fibonacci tried his level best to persuade and convince the other mathematicians to apply the system. This book is written in Latin and meticulously explains the different methods for addition, subtraction, multiplication and division. There are many different problems to further explain the process.

### The Fibonacci numbers

The Fibonacci number series includes the consecutive addition of first two numbers to give the third one. For example, 0+1=1, 1+1=2, 2+1=3 and so on. So the Fibonacci numbers are 0, 1,2,3,5,8,13, 21, and 43 and so on. Amazingly, these Fibonacci numbers have their role in Forex trade and currency marketing. They aid in the charting of curves, rectangles and triangles through which the forecasting of the forex market is done.

### Contributions

The important contribution of Fibonacci in the number theory is one of the most important incorporations in the domain of arithmetic and calculations. He conferred the following benefits.

• Implementation of square root notation.
• Introduction of bars in the fractions. Earlier, the numerator used to have quotations around it.

Later it was discovered that the Fibonacci numbers and the respective series were not only limited to the arithmetic but it also played a pivotal role in economics, commerce and trading sectors too.
