## Can you solve an expression?

An algebraic expression is a mathematical phrase that can contain numbers and/or variables. It does not contain an equals sign and cannot be solved. An algebraic equation, however, can be solved, and does include a series of algebraic expressions separated by an equals sign.

## What is common for both equation and expression?

Answer. Answer: Equations and inequalities are both mathematical sentences formed by relating two expressions to each other. In an equation the two expressions are deemed equal which is shown by the symbol =.

## What are the types of algebraic expression?

There are 3 main types of algebraic expressions which include:

• Monomial Expression.
• Binomial Expression.
• Polynomial Expression.

## How do you write an expression?

## Which of the following is an example of an algebraic expression?

For example, 2(3 + 8) is a numeric expression. Algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division). For example, 2(x + 8y) is an algebraic expression.

## How many terms are in expression?

A Term is either a single number or a variable, or numbers and variables multiplied together. So, now we can say things like “that expression has only two terms “, or “the second term is a constant”, or even “are you sure the coefficient is really 4?”

## What is a term in a sequence?

A sequence is a list of numbers in a certain order. Each number in a sequence is called a term. Each term in a sequence has a position (first, second, third and so on). For example, consider the sequence {5,15,25,35,…} In the sequence, each number is called a term.

## What is the value of the expression?

To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number. To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations.
