#### Literal equation and dimensional analysis

## What is an example of a literal equation?

A literal equation is one that has several letters or variables. Examples include the area of a circle (A=πr2) and the formula for speed (v=Dt). If the unknown variable is in the denominator, we multiply both sides by the lowest common denominator (LCD) and then continue to solve.

## What does literal equation mean?

A literal equation is an equation which consists primarily of letters. Formulas are an example of literal equations. Each variable in the equation “literally” represents an important part of the whole relationship expressed by the equation.

## Why is it called a literal equation?

One of the dictionary definitions of “literal” is “related to or being comprised of letters”, and variables are sometimes referred to as literals. So “solving literal equations” seems to be another way of saying “taking an equation with lots of letters, and solving for one letter in particular.”

## Why do we solve literal equations?

Literal equations, simply put, are equations containing two or more variables. Your goal is to solve for just one variable with respect to others.

## What is a multi step equation?

Multi-step equations are algebraic expressions that require more than one operation, such as subtraction, addition, multiplication, division, or exponentiation, to solve.

## What is meant by literal?
