Parts of Algebraic Expressions

Front

What is an algebraic expression?

Back

An algebraic expression is a mathematical phrase that includes numbers, variables, and operations. For example, 3x + 5 is an algebraic expression.

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 multiplied together. For example, in 4y + 3x + 7, the terms are 4y, 3x, and 7.

Front

What is a variable in an algebraic expression?

Back

A variable is a symbol, usually a letter, that represents an unknown value. For example, in the expression 5y + 2, 'y' is the variable.

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 2y + 3, the number 3 is a constant.

Front

What is the coefficient in an algebraic expression?

Back

A coefficient is a number that is multiplied by a variable. For example, in 4x, the coefficient is 4.

Front

How do you identify the operation in an algebraic expression?

Back

The operation in an algebraic expression is indicated by symbols such as +, -, ×, or ÷. For example, in 4y - 8, the operation is subtraction (-).

Front

What is the degree of a term in an algebraic expression?

Back

The degree of a term is the exponent of the variable in that term. For example, in 3x^2, the degree is 2.

Front

How do you count the number of terms in an algebraic expression?

Back

To count the number of terms, look for the number of separate parts in the expression, separated by + or - signs. For example, in 2y + x + 4, there are 3 terms.

Front

What is a monomial?

Back

A monomial is an algebraic expression that contains only one term. For example, 5x is a monomial.

Front

What is a binomial?

Back

A binomial is an algebraic expression that contains exactly two terms. For example, 3x + 4 is a binomial.
