Parts of algebraic expressions

Front

What is a term in an algebraic expression?

Back

A term is a single mathematical expression that can be a number, a variable, or a combination of both, such as 8x, 3y, or 10.

Front

What is the coefficient of a variable?

Back

The coefficient is the numerical factor in front of a variable in a term. For example, in 8x, the coefficient is 8.

Front

What is a constant in an algebraic expression?

Back

A constant is a fixed value that does not change. For example, in the expression 10 - y, the constant is 10.

Front

How do you identify the coefficient of a variable in an expression?

Back

The coefficient of a variable is the number that is multiplied by the variable. For example, in 7x - y, the coefficient of x is 7 and the coefficient of y is -1.

Front

What is the difference between a term and a constant?

Back

A term can include variables and coefficients, while a constant is just a fixed number without any variables.

Front

In the expression 8x + 10, what is the coefficient?

Back

The coefficient is 8, which is the number in front of the variable x.

Front

What does it mean if a variable has no coefficient?

Back

If a variable has no coefficient, it means the coefficient is 1. For example, in x, the coefficient is understood to be 1.

Front

What is the coefficient of y in the expression 3y - 5?

Back

The coefficient of y is 3.

Front

In the expression 4a + 2b + 7, which part is a constant?

Back

The constant is 7, as it does not change and has no variable.

Front

What is the term in the expression 5x + 3y - 2?

Back

The terms are 5x, 3y, and -2.
