BODMAS is a helpful acronym meaning brackets, order, division, multiplication, addition and subtraction, ensuring that equation steps are completed in the right order. A mathematical question with multiple operations may give different answers depending on the order in which it is solved.
Continue ReadingAn example of this is the equation 18 + 5 x 2, which may be interpreted as adding 18 and five then multiplying by two. This interpretation gives a different answer to the same question, so BODMAS exists to clarify when each operation should be performed. Multiplication comes before addition, therefore the equation should be solved by multiplying five and two, and then adding 18 for a total of 28.

Full Answer >The four fundamental operations in math are addition, subtraction, multiplication and division. There are corresponding symbols for each operation: the plus sign (+) for addition; the minus sign (-) for subtraction; the symbols “x”, “*” and “•” for multiplication; and the obelus (÷) and forward slash (/) for division.

Full Answer >"PEMDAS" is an acronym for the order in which operations are performed in a mathematical expression: parentheses, exponents, multiplication, division, addition and subtraction. If there are parentheses, that operation is completed first. Any exponents are taken care of next. Multiplication and division operations follow exponents, but multiplication does not outrank division. Addition and subtraction come last, and they, too, have equal stature.
