*"Work" problems usually involve situations such as two people working together to paint a house.*You are usually told how long each person takes to paint a similarly-sized house, and you are asked how long it will take the two of them to paint the house when they work together.

In these acronyms, "brackets" are the same as parentheses, and "order" is the same as exponents.

BEDMAS stands for "Brackets, Exponents, Division Subtraction" Multiplication, division, addition and subtraction are left-associative.

This means that when you are solving multiplication and division expressions you proceed from the left side of your equation to the right.

Similarly, when you are solving addition and subtraction expressions you proceed from left to right.

However, multiplication and division have the same precedence.

In other words, multiplication and division are performed during the same step from left to right. The same confusion can also happen with "AS" however, addition and subtraction also have the same precedence and are performed during the same step from left to right.

If your equation has fractional exponents or roots be sure to enclose the fractions in parentheses.

For example: If you want an entry such as 1/2 to be treated as a fraction then enter it as (1/2).

Multiplication and Division happen at the same time, from left to right.

Addition DOES NOT always get performed before Subtraction.
