An inequality describes a situation in which one quantity is greater than or less than another quantity. Unlike equations, they don't have a specific value as an answer. They show a range of values.
Example:
2x > 10 Divide by 2
When you solve that you'll get 5 and that shows that x is every number that's greater than 5.
To write an inequality, use a bar model to write and solve equations, solve an equation using the inverse operation, convert a real world situation to the problem, write an inequality from a word problem, solve inequalities with inverse operations, represent an inequality solution set on a number line.
