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.
Know MoreAn 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 >In mathematics, the range of a set of data refers to the difference between the smallest and largest number. For the set of data 1,2,3,4,7, the range is equal to 7 minus 1 or 6.
Full Answer >In mathematics the difference is the result of subtracting one number from another, and represents the operation of removing objects from a collection. Mathematicians use the term "difference," because it shows by how much the two numbers in the subtraction problem differ.
Full Answer >In mathematics, the abbreviation "exp" stands for the word exponent. An exponent is a number placed after another number to indicate the power to which the former number is to be raised. The expression 5 exp 2, for example, means 5 raised to the second power or 5 x 5.
