Order of Operations<\/strong> When evaluating an expression, proceed in this order:<\/strong><\/p>\n The proper application of “order of operations” is needed when working with such mathematical topics as evaluating formulas, solving equations, evaluating algebraic expressions, and simplifying monomials and polynomials.<\/p>\n There is a phrase that may help you to remember this order: PEMDAS<\/strong> While PEMDAS lists M before D, remember that multiplication and division are done as they are read from left to right. It may not always be the case that multiplication is done “before” division. <\/p>\n The reason (multiplication & division – MD) and (add & subtract – AS) are “grouped” in sets of parentheses is that when those operations are next to each other you do the math from left to right.<\/strong> You do not always do multiplication or addition first. It may be the case where division will be done BEFORE multiplication or subtraction will be done BEFORE addition.<\/p>\n <\/p>\n <\/p>\n Read More:<\/strong><\/p>\n
\nWhen a numerical expression involves two or more operations, there is a specific order in which these operations must be performed.

\nThe expression 16 \u00f7 4 x 2 = 8 (not 2).
\nThe same is true of addition and subtraction: 8 – 4 + 2 = 6 (not 2).<\/p>\n
