Please Excuse My Dear Aunt Sally! Order of operations. Parenthese, Exponents, Multiply & Divide, Add & Subtract. Multiplication & division comes before addition & subtraction. Does not matter if the parentheses are there or not. You multiply & divide first, then add, & subtract. PEMDAS. Pretty good observations if you got all the values right. Have never known an artist, attorney, or doc that was good at math! Close but no cigar...Think FW was the only one to hit legit. Quillback said he checked the interwebs and consulted with the deep state behind the scenes😃!
