Explanation

Data Types: Bool true/false , Num 7, 1.5e-9, Complex 2+3i, Units 3.0 cm, 2.7 kg
Vector / Matrix: v = [1, 2, 3], M = [11, 12; 21, 22]
Predefined Functions: abs(), sqrt(), sin(), log()
Own Functions: f(x) = x^2 - 5, then call f(3),

Example

f(x) = x^2 + 3x -1
fdev = derivative("x^2 + 3x -1", "x") // 2x + 3
A = [2, 1; 0, 2]
d = det(A)
