# 1.1 – Algebraic Expressions

## Key Terms

• Algebraic Expression – a mathematical expression that contains one or more variables.
• Mathematical Expression  – a collection of numbers and operations arranged in a meaningful order.
• Term – a number or variable, or the product or quotient of a number and one or more variables.
• Constant – the term in a polynomial that does not have a variable. The constant term has a degree of zero.
• Coefficients – numbers that multiply variables.
• Factor – a number or expression that is multiplied by another number or expression.

## Notes

Equivalent Fractions
• The difference between an algebraic expression and an algebraic equation is that the algebraic equation has an equal sign.

• How do you write an algebraic expression from a pattern of numbers, a table, or a graph?
• Find a mathematical rule that changes the input to the output.
• Determine if this same rule will work for all the pairs in the pattern, table, or graph.
• Write the expression using variables.
