Entering formulas for simplifier

The formulas that my simplifier simplifies, are entered the same way as in my formula plotting system. However, to simplify a formula, it needs to be understood much deeper than when we just want to draw it as a picture. Therefore, there are some important requirements.

Requirements

  • DO use multiplication sign '*' (the STAR) symbol. For the simplifier, xy is NOT the same as x*y or yx. Simplifier thinks that xy is a separate variable. Good example: x*y-y*(x+2). Bad example: xy-y(x+2).
  • DO use '*' when multiplying a variable by an expression in parentheses: x*(x+2). Otherwise, my simplifier will think that you are trying to use a function and will become confused.
  • Use parentheses liberally to avoid any ambiguity. (x+y)/(x-y) is NOT the same as x+y/x-y.

Operations

  • Use '*' (STAR) for multiplication. 2*3 is legal, 2x3 will be misunderstood.
  • Use '^' (CARET) for power. 2^3 means 2 to degree of 3, or 8.
  • Use '/' (FORWARD SLASH) for division
  • Only '(' and ')' (parentheses) are allowed for grouping terms. Curly or square brackets are used for other purposes.

Operation priority: + and - have lowest priority, * and / h

Good Examples

x*y-x*(y+2)   <-- '*' is used for multiplications
a^b*3         <-- means (a to the degree of b) multiplied by 3

Bad examples

xy-yx         <-- variable xy and variable yx are different variables
y(x-2)        <-- simplifier will think that it is function y of x-2.
