**Polynomials**


 * An expression whose terms are of the form of ax^k, where k is a non-negative integer, is a polynomial in one variable or simply a polynomial. **

** ^2 or ^3 means "squared" or "cubed" **

**3x^3+5x^2-7+x** **3x^3+5x^2+x-7**
 * Ex.1- (4x^3+3x^2)+(2x^2-1x^3+x)**

Ex.2- (3x^3-4x^2) - (3x^3+3x^2-x-4 ) -7 x^2 + x +4 Ex.3- (5x^2-10x^3+5)+(6x^2+6x^3) 11x^2-4x^3+5 - 4x^3+11x^2+5
