Introduction
There were many improvements during the Renaissance, including mathematics.Many scientists and mathematicians created new symbols and graphs, all of which we still use today. So why was Math invented? In the Renaissance people used math to keep track of animals or bundles of food. Using math was important to our ancestors to survive during the winter.
Symbols
Addition/Subtraction- Johannes Widmann, Nicole d' Oresme used the addition symbol to abbreviate the Latin word "et" which meant "and".
FUN FACT: The Egyptians did not use the addition and subtraction symbol we use today, they used a pair of legs walking to the right for addition and for subtraction they used a pair of legs walking to the left.
+/-
Division- Johann Heinrich Rahn, the symbol for division was called an "obelus".
Graphs
Logarithm- John Napier's graph, made some of the harder equations easier. This resulted in the advance in math, astronomy, and science. Napier also improved the decimal point.
Marin Mersenn's graph- Mersenn had named the graph after himself. He is very well known today, for the term "Mersenn primes".
Multiplication- William Oughtred, he was credited for more than 100 mathematical symbols. Now we only use very few of his symbols, the multiplication symbol included. Think your the only one who gets the multiplication sign and the letter "x" confused? Well, your not the only one, people back then didn't like it.
x
Equals- Robert Recorde and William Oughtred, Robert Recorde wrote about the symbol saying that he didn't want to write out "is equal to" anymore and the describing what the symbol should look like.
=
Less/ Greater than- Thomas Harriot, Oughtred and Barrow, one hundred years later Pierre Bouguer put a line under the symbol to create the symbol "greater or equal to" and "less than or equal to"
< / >
Exponent- Nicolas Chuquet, introduced the first use of complex numbers
x2
Radical (root)- Christoff Rudolff, In Italy, he had shown the world, during a math competition, first one type, then all types of cubic equations.
Girard Desargues and later on Jean Victor Poncelet and Gaspard Monge's graph. introduced projective geometry, he is known as the greatest mathematician in history, with two others; Archimedes and Gauss.
Fraction Bar - Fibonacci, real name Leonardo of Pisa.as well as the fraction bar he had many other achievements, such as the golden ratio and Lattice Multiplication.
-
Decimal Point- Francesco Pellos, was not popularized until early 17th Century.
