2 Tricks for Remembering Greater Than and Less Than Signs

What do those little sideways carat symbols mean? They’re inequalities! Inequalities can be difficult to get a handle on, especially because the greater than and less than signs look so similar. But these symbols are very useful, because they help us

show the relationship between numbers or equations

in a way that doesn’t just say that they’re equal.

In this article, we’ll be talking about what inequalities are, how they’re represented, and how to remember which sign means what.


Not knowing what the signs mean may make your math homework feel something like this.

What Are Greater Than and Less Than Signs For?

Inequalities are math problems that don’t resolve with a clear “equals” answer—instead,

they compare two things, demonstrating the relationship between them rather than showing that one is equal to another

. Hence the name; “inequality” means that two things are not equal.

We’re all familiar with the equal sign, “=” at this point in math. But “>” and “<” are not as common, let alone “≥” and “≤”.

Here’s a chart to cover all the inequality symbols





Less than—the number on the left is

less than

the number on the right;

2 < 3


Greater than—the number on the left is

greater than

the number on the right;

3 > 2

Less than or equal to—the number on the left is

less than or equal to

the number on the right;

2 or 3 ≤ 3

Greater than or equal to—the number on the left is

greater than or equal to

the number on the right;

2 or 3 ≥ 2

Does not equal—the number on the left

does not equal

the number on the right;

2 ≠ 3


Now we’ll finally get to talk about why all these photos are of crocodiles.

How to Remember Greater Than and Less Than Signs

Though the greater than and less than signs have clear meanings, they can be kind of hard to remember. All of them look similar, with the exception of the “does not equal” sign.

So how can you remember them?

Alligator Method

One of the best ways to memorize the greater than and less than signs is to

imagine them as little alligators (or crocodiles), with the numbers on either side representing a number of fish.

The alligator always wants to eat the larger number of fish, so

whatever number the mouth is open toward is the larger number



The alligator’s mouth is open toward the 4, so even if we weren’t sure that 4 is a bigger number than 3, the > sign would tell us.

All inequality signs give us the relationship between the first number and the second, beginning with the first number, so 4 > 3 translates to “4 is

greater than



This also works the other way around. If you see 5 < 8, imagine the < sign as a little alligator mouth about to chomp down on some fish.

The mouth is pointed at the 8, which means that 8 is more than 5.

The sign always tells us the relationship between the first number and the second, so 5 < 8 can be translated to “5 is

less than


When you’re working with inequalities, you can even draw little eyes on the symbols to help you remember which means which. These can be tricky to remember, so

don’t be afraid to get a little creative until you really have them memorized!


Rotate your less than sign a little bit and you get an L for “less than!”

L Method

This method is pretty simple—

”less than” starts with a letter L, so the symbol that looks most like an L is the one that means “less than.”

< looks more like an L than >, so < means “less than.”

Because > doesn’t look like an L, it can’t be “less than.”

Equal Sign Method

Once you’ve mastered the Alligator or L method, the other symbols are easy!

“Greater than or equal to” and “less than or equal to” are just the applicable symbol with half an equal sign under it.

For example, 4 or 3 ≥ 1 shows us a greater sign over half an equal sign, meaning that 4 or 3 are

greater than or equal to


It works the other way, too. 1 ≤ 2 or 3 shows us a less than sign over half of an equal sign, so we know it means that 1 is

less than or equal to

2 or 3.

The “does not equal” sign is even easier!

It’s just an equal sign crossed out.

If you see an equal sign crossed out, it means that the equal sign doesn’t apply—thus,

2 ≠ 3

means that 2 does not equal 3.


Keep these things in mind and you’ll look this happy about working with inequalities.

Key Tips For Working With Inequalities

Inequalities are tricky—we’re used to having a clear and concrete answer for math problems, but inequalities don’t always give us that. When you’re working with inequalities,

keep these things in mind to help ease you through the process.

Inequalities are All About Relationships

Keep in mind as you’re working on inequalities that

they’re typically asking you to solve for a relationship or to identify which symbol is appropriate

rather than asking you to solve for a single number. You don’t need to end up with two numbers on either side of an equal sign to be right—the answer just needs to be true.

Isolate Your Variables

When you’re working with inequalities with variables, it’s important to remember that, in general, you’ll be trying to

isolate the variable to one side or the other.

Focus on condensing numbers and canceling things out when you can, always with the goal of getting the variable alone on either side of the equation.

Negative Numbers Change the Greater Than or Less Than Sign

Don’t forget that performing certain actions will flip the sign.

When you multiply or divide by a negative number, you need to flip the “greater than” or “less than” sign along with it.

Don’t Multiply or Divide by a Variable—Most of the Time

Unless you know for certain that a variable will always be positive or always be negative,

don’t multiply or divide an inequality by a variable
