|---|---|---|
| Property | Description | WIRIS documentation |
| Has integer form | Checks whether the answer is a single integer, possibly with sign. | More details |
| Has fraction form | Checks whether the answer is a single fraction or integer, possibly with a sign. | More details |
| Has polynomial form | Checks whether the answer is syntactically a polynomial with real or complex coefficients, i.e., it consists only of sums, products, natural powers, variables, and constants. | More details |
| Has rational function form | Checks whether the answer has the form of a rational function: sums, products, powers, and quotients. | More details |
| Is a combination of elementary functions | Checks whether the answer is a combination of elemental functions: there are no operators such as the integral operator, the derivative operator, infinite sums or products, etc. | More details |
| Is expressed in scientific notation | Checks whether the answer is in scientific notation. | More details |
