## Expression syntax ## Expression syntax
Expression can contain numbers or variable names with functions applyed to them, separated with operators or united with braces. Expression can contain numbers or variable names with functions applied to them, separated with operators or united with braces. Numbers do not support `*`-less multiplication with spaces. Variables must be separated by space.
Here are examples with `_` as space
| Wrong | Right |
|--|--|
| `2_a` | `2a` or `2*a` |
| `a_2` | `a*2` |
| `a_2_a` | `a*2*a` |
| `2_cos(a)` | `2cos(a)` or `2*cos(a)` |
| `cos(a)_2` | `cos(a)*2` |
| `aa` | `a*a` or `a_a` |
| - | `cos(a)cos(a)` or `cos(a)_cos(a)` or `cos(a)*cos(a)` |
