© Boardworks Ltd of 60 Dividing terms Remember, in algebra we do not usually use the division sign, ÷. Instead we write the number or term we are dividing by underneath like a fraction. For example, ( a + b ) ÷ c is written as a + b c
© Boardworks Ltd of 60 Like a fraction, we can often simplify expressions by cancelling. For example, n 3 ÷ n 2 = n3n3 n2n2 = n × n × nn × n × n n × nn × n = n 6 p 2 ÷ 3 p = 6p26p2 3p3p = 6 × p × p 3 × p = 2 p Dividing terms

Section 2.1 Linear Equations in One Variable. Equation Equation- a mathematical expression that states that two (2) quantities are equal ** Use the equal.
ALGEBRAIC EXPRESSIONS Step 1Write the problem. Step 2Substitute in the values for the unknown (variable). Step 3Use PEMDAS (remember to go left to right).
Simplifying Rational Expressions We are trying to get common terms to factor ( cancel ) to = 1. You might have to distribute or FOIL to get started. ALWAYS.
