Order of OperationsDate: 8/21/96 at 21:20:53 From: Anonymous Subject: Order of Operations How do I solve (8.2-3.6)(3*3.6+6)? Date: 8/22/96 at 11:49:14 From: Doctor Leigh Subject: Re: Order of Operations Thank you for your question. The order of operations is: Parenthesis Exponents Multiplication Division Addition Subtraction To help myself think of this I remember a saying that was taught me. It is "Please excuse my dear aunt Sally". You may notice that the first letter of each word matches the first letter in each of the operations. So...now to solve your problem. (8.2-3.6)(3*3.6+6) Parenthesis first... (4.6)(3*3.6+6) Since no exponents, then multiplication... (4.6)(10.8+6) Then since no division, addition... (4.6)(16.8) Finally, since we are all done inside the parenthesis. 77.28 is the answer -Doctor Leigh Ann, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
