This lesson covers the definition of algebraic expressions and their components, including terms and coefficients. It explains how to identify like terms, perform arithmetic operations on similar terms, and simplify expressions by inserting or removing brackets.

• 08:47 “Now, to say further on that, I'm going to talk about coefficients. Coefficient is the number or factor that has been multiplied by the variable. In this expression, minus four x, the coefficient is minus four. In this ex...”
• 23:10 “So you have minus 2 into bracket 3m plus we have minus 2. So you bracket it out. 5. So minus 2 times 3m is minus 6m. Now you should remember the rules of multiplication, the rules you use in multiplying addition and subt...”
• 09:35 “addition operator. It's a plus sign. Without negative, it is positive. So here we have minus four x. And here, the coefficient is minus four, while this is a constant. Another example, if you have three x plus two, this...”
