Polynomial comes from poly- (meaning "many") and -nomial (in this case meaning "term") it means "many terms".


A polynomial can have constants, variables, and exponents. They can be combined using addition, subtraction, multiplication and division. 

These are polynomials:

x - 2
-6y2 - (7/9)x
3xyz + 3xy2z - 0.1xz - 200y + 0.5
512v5+ 99w5

Mathematics is a core academic subject. In the real world, algebra and calculus concepts are essential to career paths in the areas of construction, architecture, aerospace and financial planning.
