- These are the operations: +, -, *, /. Those symbols are mandatory in the expressions, for example: 2x instead of 2*x will generate an error.
- We can add two lists: [1,2,3]+[4,5] will give [5,7,3].
- We can subtract two lists: [1,2,3]-[4,5,6,7] will give [-3,-3,-3,-7].
- A list may be multiplied by a complex: 5*[1,2,3] will give [5,10,15], but [1,2,3]*5 will give 5.
- A list may be divided by a complex: [1,2,3]/2 will give [0.5,1,1.5].
- The operation x^y is corresponding to the power function ${x}^{y}$. The exponent has to be real, but when $x$ is a non real complex, $y$ must be an integer.
