Parts of an Expression

Front

What is a coefficient in an expression?

Back

A coefficient is a numerical factor that multiplies a variable in an expression.

Front

Front

What is the coefficient of x in the expression 6 - x + 8?

Back

The coefficient of x is -1.

Front

List the terms in the expression 7x - 6 + 8.

Back

The terms are 7x, -6, and 8.

Front

What are variables in an expression?

Back

Variables are symbols (like x, y, a, etc.) that represent unknown values.

Front

Back

A constant is a number that does not change and has no variable attached to it.

Front

How do you identify the terms in an expression?

Back

Terms in an expression are separated by plus (+) or minus (-) signs.

Front

What is the difference between a term and a coefficient?

Back

A term is a single mathematical expression (like 5x or -6), while a coefficient is the numerical part of a term that multiplies a variable.

Front

In the expression 3x + 4y - 5, what are the coefficients?

Back

The coefficients are 3 (for x) and 4 (for y).

Front

What is the role of parentheses in expressions?

Back

Parentheses indicate that the operations inside them should be performed first according to the order of operations.
