gmdas example and solution
Answer (1)
GEMDAS stands for: G ----> Grouping (Parentheses) E ----> Exponents M ----> MultiplicationD ----> DivisionA -----> AdditionS -----> SubtractionImportant Notes :1. In a particular simplification, if you have both multiplication and division, do the operations one by one in the order from left to right.2. Multiplication does not always come before division. We have to do one by one in the order from left to right. 3. In a particular simplification, if you have both addition and subtraction, do the operations one by one in the order from left to right.EXAMPLE: [tex]12/(2^{2}) + 5 X (6-4)^2[/tex]GROUP:Solve inside the parenthesis first.[tex]2^{2}[/tex] = 4(6-4) = 2Substitute:[tex]12 / 4 + 5 X (2)^2\\[/tex]EXPONENT:Solve numbers with exponent..[tex]2^2[/tex] - 4Substitute:12 / 4 + 5 X 4MULTIPLICATION AND DIVISION:Remember the rule, left to right.12 / 4 = 35 X 4 = 20Substitute:3 + 20ADDITION/SUBTRACTION:3 + 20 = 23FINAL ANSWER: 23
