Answer: In each of the terms 3x 2 and 7x, x is a variable, and in both terms, we are

**multiplying a number by the variable**. In the first term, 3x 2, 3 is being multiplied by the variable, so 3 is a coefficient. In the second term, 7x, 7 is being multiplied by the variable, so 7 is a coefficient.## What is a basic expression?

Expressions are basically

**the building blocks of Statements**, in that every BASIC statement is made up of keywords (like GOTO, TO, STEP) and expressions. So expressions include not just the standard arithmetic and boolean expressions (like 1 + 2), but also lvalues (scalar variables or arrays), functions, and constants.## How do you find expressions?

## What are the parts of an expression?

A mathematical expression is an expression that contains numbers, variables, symbols, and operators connected with addition, subtraction, multiplication, and division. Each mathematical expression has different parts. Three of these parts are

**terms, factors, and coefficients**.## How do you write an expression for a word problem?

## How do you write an algebraic expression in word?

## What are the factors in an expression?

A factor in an expression is

**something that is multiplied by something else**. It can be a number, variable, term or any other longer expression. For example, the factors of 2xy are 2, x and y.## What are the terms in an expression?

A term is a single mathematical expression. It may be

**a single number (positive or negative), a single variable ( a letter ), several variables multiplied but never added or subtracted**. Some terms contain variables with a number in front of them. The number in front of a term is called a coefficient.## How do you simplify expressions?

**To simplify any algebraic expression, the following are the basic rules and steps:**

- Remove any grouping symbol such as brackets and parentheses by multiplying factors.
- Use the exponent rule to remove grouping if the terms are containing exponents.
- Combine the like terms by addition or subtraction.
- Combine the constants.
