# What is the meaning of like terms?

“Like terms” are terms whose variables (and their exponents such as the 2 in x2) are the same. In other words, terms that are “like” each other. Note: the coefficients (the numbers you multiply by, such as “5” in 5x) can be different.

Similarly, it is asked, what are examples of like terms?

In algebraic expressions, like terms are terms that contain the same variables raised to the same power. Only the coefficients of like terms are different. Since adding or subtracting unlike terms is like mixing apples and oranges — only like terms can be combined.

What are the rules for combining like terms?

Combining like terms is a mathematical process used to simplify an expression or to add or subtract polynomials. Learn how to recognize like terms and combine them in this lesson, then check your knowledge with a quiz. High School Algebra I: Help and Review / Math Courses.

## How do you simplify the expression?

Here are the basic steps to follow to simplify an algebraic expression:

• remove parentheses by multiplying factors.
• use exponent rules to remove parentheses in terms with exponents.
• combine like terms by adding coefficients.
• combine the constants.
• ## What is the definition of the distributive property?

The distributive property is one of the most frequently used properties in math. In general, this term refers to the distributive property of multiplication which states that the. Definition: The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.

## What does it mean to substitute in math?

In Algebra “Substitution” means putting numbers where the letters are.

## What does the term coefficient mean in math?

A number used to multiply a variable. Example: 6z means 6 times z, and “z” is a variable, so 6 is a coefficient. Variables with no number have a coefficient of 1. Example: x is really 1x. Sometimes a letter stands in for the number.

## What is the definition of a numerical expression?

Definition of Numerical Expression. The term “numerical” means “involving numbers” and the term “expression” means “phrase”. A numerical expression is a mathematical phrase involving only numbers and one or more operational symbols.

## Can you add like terms with different exponents?

You cannot combine the x2 and 2x, because the first term has an exponent (2) and the second one does not have an exponent; therefore, you cannot add them together! When combining like terms, you must make sure than all the variables, and exponents, are the same before you add them together.

## Are these terms like or unlike?

In algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers. The order of the variables does not matter unless there is a power.

## Can you multiply with unlike terms?

Unlike Terms are any terms that don’t have the same base(s) to the same exponent(s). You can multiply and divide unlike AND like terms. One form of simplifying polynomials is adding and subtracting like terms. However, you can ONLY add and subtract like terms.

## Do you add like terms?

When adding and subtracting like terms, all we really need to do is combine the coefficients. For example, we can simplify the expression 3x + (-9x) by combining both of those x terms. Look Out: we can only combine terms with the exact same variables with the same exponents!

## Are XY and YX like terms in algebra?

Like terms are terms that contain the same variables raised to the same power. Only the numerical coefficients are different. Terms obey the associative property of multiplication – that is, xy and yx are like terms, as are xy2 and y2x. The expressions on the right have had their like terms combined.

## What are the rules for combining like terms?

Combining like terms is a mathematical process used to simplify an expression or to add or subtract polynomials. Learn how to recognize like terms and combine them in this lesson, then check your knowledge with a quiz. High School Algebra I: Help and Review / Math Courses.

## How do you use the distributive property?

The distributive property of multiplication over addition can be used when you multiply a number by a sum. For example, suppose you want to multiply 3 by the sum of 10 + 2. According to this property, you can add the numbers and then multiply by 3.

## What is the meaning of constant term?

In mathematics, a constant term is a term in an algebraic expression that has a value that is constant or cannot change, because it does not contain any modifiable variables. For example, in the quadratic polynomial. the 3 is a constant term.

## What is the coefficient of the term?

The coefficients are the numbers that multiply the variables or letters. Thus in 5x + y – 7, 5 is a coefficient. It is the coefficient in the term 5x. Also the term y can be thought of as 1y so 1 is also a coefficient. Like terms are terms that contain the same variable raised to the same power.

## What does it mean to simplify the expression?

Simplifying Algebraic Expressions. By “simplifying” an algebraic expression, we mean writing it in the most compact or efficient manner, without changing the value of the expression. This mainly involves collecting like terms, which means that we add together anything that can be added together.

## What is the definition of term in math?

In Algebra a term is either a single number or variable, or numbers and variables multiplied together. Terms are separated by + or − signs. See: Variable.

## What is the coefficient of a number?

A number or symbol multiplied with a variable or an unknown quantity in an algebraic term. For example, 4 is the coefficient in the term 4x, and x is the coefficient in x(a + b). A numerical measure of a physical or chemical property that is constant for a system under specified conditions.

## What is the definition of constant in math?

In Algebra, a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number. Example: in “x + 5 = 9”, 5 and 9 are constants. If it is not a constant it is called a variable. See: Variable. Algebra – Definitions.
