To help students in the United States remember this order of operations, teachers drill the acronym PEMDAS into them: parentheses, exponents, multiplication, division, addition, subtraction. Other teachers use an equivalent acronym, BODMAS: brackets, orders, division and multiplication, and addition and subtraction.

So if you were to check this you would take this negative 1/2.

The following steps provide a good method to use when solving linear equations. Simplify each side of the equation by removing parentheses and combining like terms. Use addition or subtraction to isolate the variable term on one side of the equation. Use multiplication or division to solve for the variable.

Remember PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. In most numerical problems, you would start with parentheses and continue with the steps to the right.

Some academic styles require important mathematical expressions to be numbered for reference, much like figures and tables. For proper formatting, keep the equation left-aligned; indent by a half-inch; and after the equation, enter the relevant reference number, enclosed in parentheses, close to the right-hand margin.

We have 4 ways of solving one-step equations: Adding, Substracting, multiplication and division. If we add the same number to both sides of an equation, both sides will remain equal. If we subtract the same number from both sides of an equation, both sides will remain equal.
