What is an algebraic expression?
An expression that contains numbers, operations, and one or more symbol.
What are the parts of an algebraic expression called?
terms
Example: 3+ 2x + 7y
3, 2x, and 7y are the terms; terms are separated by addition and subtraction signs
What are symbols called that represent one or more numbers?
variable
Example: 3+ 2x + 7y
x and y are the variables.
What is the numerical factor of a term that contains a variable called?
coefficient
Example: 3+ 2x + 7y
2 and 7 are the coefficients
What are the terms called without a variable?
constant
Example: 3+ 2x + 7y
3 is the constant
