Algebraic Expression & Distance, Rate, and Time

Algebraic expression is formed when variables and constants are combined by the use of the four fundamental operations.

A constant is a number with a fixed value.

The numerical coefficient is the letter factor of a term

Terms consisting of constants only are UNLIKE terms

Like terms have the same variables but those variables have different exponents.

A variable without a number has 0 as its numerical coefficient.

An algebraic expression does not use an equal (=) sign.

The expression “less than” is the same as the expression “is less than”.

For the phrases “added to” and “more than”, the arrangement of the terms is reversed

In the expression 2x + 10y + z, there are three terms.
