2 + 3 * 4
; The answer is then displayed.  Notice that the multiplication
; was completed before the addition because of the precedence rules.
; The answer can also be stored in variables and used later by
; refering to the variable names.
x = 2 + 3 * 4
y = sqrt(x)          ;'y' gets the square root of 'x'
!list
; Because variable 'y' is defined in terms of variable 'x', changing
; variable 'x' will automatically change variable 'y'.
