Calculate

This table shows operators with one example each for Octave-mode (O-mode) and Maxima-mode (M-mode). Operations are executed according to their precedence (prec), and, if these are equal, in order.
Function O-Mode M-Mode Prec Order
Addition x + y x + y 4 left-right
Subtraction x - y x - y 4 left-right
Scalar Multiplication x .* y x * y 3 left-right
Vector/Matrix Multiplication x * y x . y 3 left-right
Scalar Division x ./ y x / y 3 left-right
Matrix Division (right) x / y 3 left-right
Matrix Division (left) x \ y 3 left-right
Scalar Exponentiation x .^ y x ^ y 1 left-right
Vector/Matrix Exponentiation x ^ y x ^^ y 1 left-right
Range x:y:z 5 left-right
Assignment x = z x : y 10 right-left
Assignment x += z 10 right-left
Assignment x -= z 10 right-left
Assignment x /= z 10 right-left
Assignment x *= z 10 right-left
Preincrement ++x ++x 10 left-right
Predecrement --x --x 10 left-right
Postincrement x++ x++ 10 right-left
Postdecrement x-- x-- 10 right-left
Adjunct x' 1 right-left
Factorial x! 1 left-right
