Parenthesis, Exponents (powers, square roots), Multiplication, Division, Addition, Subtraction. Remember, when working with algebra, we must still apply the order of operations, PEMDAS. In terms of x – rewrite the equation in the form x =….Expand – multiply out the expressions inside parentheses.Simplify – collect together like terms to make the expression or equation look simpler.Binomial – a binomial or binomial expression is one which has two parts, like our example 4c + 2.For example, for 4c + 2, 2 is the constant. Constants – values which are not variable and stay the same. ![]() For example, in the expression 4c + 2, 4 is the coefficient. Coefficients – the amount a term has been multiplied by.Substitute – put the values you have been given into the algebraic expression.Solve the equation – find out the value of the unknown. ![]() Here are some of the key terms along with what they mean: When you are presented with an algebraic problem it is important to establish what you are being asked to do, especially if it is on a math test. Later, we develop these techniques to allow us to deal with more complicated polynomials and math problems such as ones that involve quadratic equations or a system of equations, so it is important to establish a solid foundation. In middle school we learn to write and manipulate basic algebraic expressions and linear equations. There are many topics and techniques within algebra.
