When more than one arithmetic operator is involved in a formula, Excel follows the same basic order of operations that you use in algebra. Moving from left to right in a formula, theorder of operationsis as follows: first negation (-), then all percentages (%), then all exponentiations (^), then all multiplications (*) and divisions (/), and finally, all additions (+) and subtractions (-).
As in algebra, you can use parentheses to override the order of operations. For example, if Excel follows the order of operations, 8 * 3 + 2 equals 26. If you use parentheses, however, to change the formula to 8 * (3 + 2), the result is 40, because the parentheses instruct Excel to add 3 and 2 before multiplying by 8.

Most people agree that charges for computer system usage should be fair, but few can define precisely what “fairness” is.Another attribute of charging schemes, but one which is easier to define, is predictability.We want to know that if a job costs a certain amount to run once, running it again in similar circumstances will cost approximately the same amount. Suppose that in a multiprogramming environment we charge by wall clock time, i.e., the total real time involved in running the job from start to completion.Would such a scheme yield predictable charges?Why?
