# How to input a polynomial

### Variables

For the polynomial calculator the default variable is 'x'; example:3x^4+5x^2-x+14

### Arithmetic operations

Power: '^'; example: x4 = x^4
Multiplication; example: 3x4 = 3x^4 .   3x4 can also be written 3*x^4
Addition: '+'; example: 3x4 + 2x3 = 3x^4 + 2x^3
Subtraction: '-'; example: 3x4 + 2x3 - x = 3x^4 + 2x^3 - x

### Restrictions

The coefficients of the terms must be real numbers , NOT expressions like: 2/3x^2 (you should input 0.666x^2) or (2*3)x^2 (you should input 6x*2) or (2-3)x^2 ( you should input -x^2 ) or (3-2)x^2 (you should input x^2).
The powers of the variable must be positive integers , like x^4, x^2, x^67. Do NOT use negative numbers, expressions or floating point numbers here.
Do not use paranthesis of any kind.
Do not use mathematical expressions of any kind (sin, cos, 2/3, (3-2), (2-3), 2*3, e^3, ln, log, tan, cot, arcsine, arccos , etc.). Use only numbers .

### Examples

x3+3x2+x-5   must be input   x^3+3x^2+x-5
2x5+54x2+(3/10)x-5.2   must be input   2x^5+54x^2+0.3x-5.2
