2000 BCE in the Middle East.
Why does 1+1=2?
Our modern understanding of the equation 1+1=2 relies upon the European inheritance of Hindu-Arabic numerals, as well as the subsequent development and dissemination of mathematical symbols. It also relies on the use of a number base greater than two; in other words, not binary, in which the symbol for two is 10.
When does 4(x+3)^2 + 5= Square root of 9(2+6+7+8)?
To answer the original question when x+1. The techniques of algebra allow us to solve problems such as this without recourse to using lines, areas, and circles as the Greeks did, and these techniques can be applied to very abstract problems that are not necessarily grounded in the physical world but exists on the realm of pure mathematics.
What is Calculus?
Calculus is an advanced form of mathematical calculations that allows one to work with the very large and the very small. The two main branches of calculus are integral calculus which gives you the area under a curve, and differential calculus, which allows you to measure the slope of a curve at any point.
Who was Pythagoras?
Pythagoras (c. 570-475 B.C.E.) was a Greek mathematician who studied geometry and mathematics in Ionia and Egypt and founded a scholarly community in southern Italy. He is credited with a theorem that describes the ratios off the sides of a right - angled triangle, and he and is followers raised the profile of mathematics as a philosophical, even religious discipline.
Where was the Metric System Invented?
The metric system of weights and measures was invented in France in the 18th century, it is now used in almost every country and in all scientific fields as it is easy to use calculations, it is based on unchanging physical constants, and it relates all units within it to each other.
