DQ2 Week 1 Please respond to this discussion question by Saturday Day 5 When using the formula NI U P VCu FC in which order must you complete the calculation Why does the order of operations matter Which order must you complete the calculation NI U P VCu FC 1 2 P VCu U times quantity total in item one 3 Quantity item 2 FC NI Variables within parenthesis are handled first due to hierarchical rules Nested parenthesis within the brackets are first then within the brackets and lastly the subtraction of the variable FC If not taken in order the answer will be different The distributive law says U P VCu U P U VCu Here the values of the multiplication are taken first and the results subtracted Example If U 2 P 5 VCu 10 and FC 1 U P VCu P VCu 5 10 5 5 U 5 2 10 10 FC 10 1 11 Distributive Law U P U VCu U P 2 5 10 U VCu 2 10 20 10 20 10 10 FC 10 1 11 Therefore the distributive law is proven Why does the order of operations matter Keeping the order of the variables is very important If reversed the sign of 10 20 10 does not equal sign of 10 10 20 Keeping the hierarchical rules is important 1 Parentheses 2 Powers and Roots exception sometimes where squareroot s of equations it is assumed to do the equation first 3 Multiplication and Division 4 Addition and Subtraction In computer programing this is basic knowledge of how a computer does mathematical calculations It is an ANSI standard Failing to follow these rigid rules will achieve errors in the output
