This equation was founded by the French mathematician Veda. /kloc-in the 6th century, with the appearance of various mathematical symbols, the concept of "equation with unknowns" appeared after French mathematicians returned to Veda to create systematic symbols for answering unknown quantities and known quantities.

History of the equation:

First, about 3600 years ago, the ancient Egyptians wrote down mathematical problems on papyrus, which involved equations with unknowns.

Second, around 825 AD, Al-Hualazimi, a mathematician in Central Asia, wrote a book called "Eliminating Elements and Returning", focusing on solving equations.

Bai Shangshu noted in Nine Chapters of Arithmetic Equation that "Fang" is a square and "Cheng" is an expression or an expression. In a problem, if there are several related data, arranging these related data side by side into a square is called' equation'.

Extended data:

An equation must be an equation, but an equation is not necessarily an equation.

Example: a+b= 13 conforms to the equation, and there are unknowns. This is an equation and an equation.

1+ 1=2 , 100× 100= 10000。 These two formulas are consistent with the equation, but there are no unknowns, so they are not equations.

In the definition, the equation must be an equation, but there can be other equations, such as 1+ 1 = 2,100×10000 =10000, all of which are equations. Obviously, the range of the equation is larger.
