Linux Command Line – Shell Scripts: Using parentheses ( ) in bc to change the calculation order

This video was created for students in my college class on using the Linux/UNIX command line (tonysako.com). In this video you will learn how to use ( ) parentheses in bc to change the order of precedence for calculations. Normally bc follows the regular math precedence of multiplication and division before addition or subtraction. However, just like in real world math, you can use parentheses to group operations and change the order.
