How to use coordinate of operations.What does any kind of read have to do with math? Its just left to right isnt it? Wrong, the order of operations is a specific method to figuring out the place answer to certain problems. For those of you who do not realize what I am yammering on about, this procedure piece is about the order of operations. The order of operations is a method used to ensure that a group of throng gets the correct answer without dispute, the order of operations is extremely useful. Without knowing the order of operations tell me, does this problem look sensible? 67-9(6-1)+48/ ((9x (5+2)-7 Didnt think so. The order of operations works like this First any intimacy in the parentheses, wherefore we do the exponents/roots, then any multiplication and division- which is done in that order, then we do Addition and Subtraction- in that order as well. To inform this, we will solve the problem above gait 1. The beginning thing you do in the order of operations is to do anything listed in parentheses, entirely you must also keep in mind everything else. So the first set we do is (5+2), even though it is the last set, addition comes first on the order of operation list. So, (5+2)= 7 right? Right, keep that in mind. Now we do the first set of parentheses, which is (6-1) which is 5. So replace some(prenominal) of those sets with (5) and (7) in that order.Step 2. The next step is to get rid of those stiff square roots and exponents. So, first we do the square root of 9, which is 3. because we perform the sacred exponent figuring. So 7 squared (7) is 49. So by now the expression should look like this 67-9 (5) +48/ 3x (7)-49.Step 3. Now we multiply and divide all the stuff together so first we do 48/3, which is 16. Then we multiply what is needed, in this object lesson it is 3x7, which is 21. Are you following me so far? Excellent if not then read it over.
