Mathematical Symbols Available In WeBWorK

+ Addition
- Subtraction
* Multiplication can also be indicated by a space or juxtaposition, e.g. 2x, 2 x or 2*x, also 2(3+4).
/ Division
^ or **       You can use either ^ or ** for exponentiation, e.g. 3^2 or 3**2
( and ) You can also use square brackets, [ ], and braces, { }, for grouping, e.g. [1+2]/[3(4+5)]

WeBWorK is case sensitive. Do NOT write "X" when you really intend "x".
