—There are 2 different priorities of arithmetic expression

—High Priority: * / %

—Low Priority: + -

—

—The equation is evaluated in two passes

—First pass: High priority operators

—Second pass: Low priority operators

Expression: x=9-12/3+3*2-1

—1st Pass

x=9-4+3*2-1

x=9-4+6-1

—2nd Pass

x=5+6-1

x=11-1

x=10
