Pre-Algebra is the preparation course for the study of Algebra providing the basic arithmetic and geometry skills needed. Pre-Algebra is for upper primary/lower secondary level school students. There are 13 modules and 116 lesson topics.
In this lesson, we’re going to dive into the basics of algebra—a powerful tool for solving problems and understanding patterns in math.
Are symbols used to represent unspecified numbers or values.
In the algebraic expression 4s, the letter s is called a variable.
Consists of one or more numbers and variables along with one or more arithmetic operations.
5x | 3x – 7 |
m × 5n | 3ab – 5cd |
In each expression, the quantities being multiplied are called factors.
In each expression, the result of the multiplied factors is called the product.
Write an algebraic expression for 5 less than a number c. The words less than suggest subtraction.
| a number c | less | five |
| c | − | 5 |
Write an algebraic expression for 9 plus the product of 2 and the number d. Plus implies add, and product implies multiply.
| 9 | plus | the product of 2 and the number d |
| 9 | + | 2d |
In this lesson, we’ll learn how to translate verbal phrases into mathematical expressions. Discover how words like ‘sum,’ ‘difference,’ ‘product,’ and ‘quotient’ connect to math operations, and practice turning everyday language into expressions using symbols, numbers, and variables.
