What Does the Crocodile Symbol Mean in Maths? Expressions!
In mathematics, the crocodile symbol, also known as the inequality symbol, is used to represent the inequality between two values or expressions.
There are two types of inequality symbols: the less-than symbol (<) and the greater-than symbol (>).
The crocodile symbol is an analogy used to help remember which symbol represents which type of inequality. The open side of the symbol represents the mouth of a crocodile, which always opens toward the larger value.
For example, if you see the less-than symbol (3 < 5), you can imagine the crocodile’s mouth opening towards the larger number (5) to indicate that 3 is less than 5.
Inequalities are an essential part of mathematics and are used to compare the relative size of two values or expressions.
The crocodile symbol serves as a helpful mnemonic to recall and comprehend the concept of inequalities.
By visualizing the mouth of the crocodile opening towards the larger value, students and mathematicians alike can more easily understand and apply this concept in various mathematical contexts.
3 Symbols: Crocodile in Mathematics Meanings
| Symbol | Name | Mathematical Meaning |
|---|---|---|
| Crocodile | Inequality symbols | In mathematics, crocodile symbols are actually known as inequality symbols. They are mainly used to compare two values. There are two types of crocodile symbols, as explained below: |
| < | Less than | Indicates that the value on the left is smaller than the value on the right. Example: 4 < 7 |
| > | Greater than | Indicates that the value on the left is larger than the value on the right. Example: 9 > 6 |
Note: The term “crocodile symbol” is an informal way people, especially younger students, refer to the inequality symbols in mathematics, because both the less than (<) and greater than (>) symbols resemble a crocodile’s mouth.

Key Takeaway
Four Facts About: The Symbolic Meaning of the Crocodile in Mathematics
What Is The Crocodile Symbol And Its Meaning In Mathematics
Explanation Of The Crocodile Symbol In Maths
The crocodile symbol is a mathematical symbol used to represent inequality. It is predominantly used in elementary mathematics, but can also be applied in higher-level math as well.
The crocodile symbol looks like an alligator or crocodile’s jaw opening towards the larger number.
The greater-than sign is similar, but the jaw ‘eats’ the smaller number.
The symbol is read as “is greater than” and has the same meaning as the “>” symbol. It is important to note that the open part of the crocodile’s mouth always points to the larger number.
Therefore, if the open end faces right, the larger of two numbers is on the right, and the smaller number is on the left.
Some examples of how to use the crocodile symbol in math are as follows:
- 5 > 3 (five is greater than three)
- 7 + 4 > 8 – 2 (the sum of seven and four is greater than the difference between eight and two)
- 2x + 1 > 7 (two times x plus one is greater than seven)
Brief History Of The Crocodile Symbol In Maths
The origin of the crocodile symbol in math is somewhat unclear. However, it was first introduced in the 16th century in europe and is now a universal symbol taught in introductory math courses worldwide.
The symbol was first used in the book “artis analyticae praxis” by michael stifel, a german mathematician in 1544. He used the crocodile symbol to represent the inequality.
The crocodile symbol’s history is interesting, as it has been modified over time and used differently in different parts of the world.
In the united states, it is known as the “greater than” symbol, while in other countries, it is simply called the “crocodile symbol” due to its resemblance to a reptile.
Overall, the crocodile symbol is an important part of elementary and higher-level mathematics, representing inequality, and is widely used across the globe.
Applications Of The Crocodile Symbol In Maths
The crocodile symbol may seem unusual in maths, but it has significant importance in various mathematical operations, often used to compare numbers.
So why is it so essential? And how is it applied in these operations? Let’s dive in and find out!
Understanding The Importance Of The Crocodile Symbol In Mathematics
The crocodile symbol is a mathematical representation of the greater than (>), less than (<), and equal to (=) symbols. It’s often depicted as a hungry crocodile or an alligator, with an open mouth indicating the larger quantity.
How The Crocodile Symbol Is Used In Mathematical Operations
Some of the ways the crocodile symbol is used include:
- Comparing numbers: The crocodile symbol is often used to compare two numbers and determine their relationship, whether one is greater than or less than the other. For instance, 7 > 5 means seven is greater than five.
- Order of operations: The crocodile symbol helps determine the correct order of mathematical operations, especially in fractions. It indicates which number is the denominator, and that the numerator should be divided or multiplied with it.
- Inequalities: Inequalities are mathematical expressions where two values are not equal. The crocodile symbol is used to depict the relationship between them. For instance, x+3 < y-2 is read as x plus three is less than y minus two.
- Probability: In probability, the crocodile symbol can be used to find the likelihood of an event. For example, if there’s a 60% chance of a team winning a game, the crocodile symbol can be used to determine the probability of the team losing.
The crocodile symbol has a vital role in mathematics. It’s used to compare numbers, determine the right order of operations, depict inequalities, and calculate probabilities.
With its intuitive visual representation, the crocodile symbol simplifies math computations and makes solving equations easier.
The Crocodile Symbol In Relation To Comparison Operators
Comparison Operators And Their Role In Mathematics
Mathematics often involves making comparisons between variables, numbers, and equations. This is where comparison operators come into play. They are symbols that help us compare two values and determine the relationship between them.
Common comparison operators in math include:
- Equal to (==)
- Not equal to (!=)
- Greater than (>)
- Less than (<)
- Greater than or equal to (>=)
- Less than or equal to (<=)
These operators are used to compare values, assess their relationship and come to a result. For instance, if we have two numbers 5 and 8, we can use the greater than symbol (>) to compare them and determine that 8 is greater than 5.
Understanding How The Crocodile Symbol Is Used As A Comparison Operator
In mathematics, particularly in elementary school, the crocodile symbol is used as a comparison operator. It is also commonly referred to as the less than or greater than symbol. But why a crocodile, you may ask?
Well, it’s because the crocodile’s open mouth resembles the greater-than/less-than symbol.
The crocodile symbol is used specifically to compare two numbers. The open mouth of the crocodile always points towards the larger of the two numbers.
For instance, if we have two numbers 9 and 4, we can use the crocodile symbol to compare them.
- 9>4
The open mouth of the crocodile faces towards the larger number, which is 9. If we reverse the order of the two numbers, the crocodile’s orientation also reverses accordingly.
- 4<9
Now the open mouth of the crocodile faces towards the smaller number, which is 4.
The crocodile symbol is a great way for young learners to understand and remember the concept of comparison operators. It’s easy to understand and has a fun visual appeal.
The crocodile symbol is a useful and memorable symbol used to teach young learners about comparison operators in math.
It’s a fun and engaging way to introduce the concept of comparing values and understanding their relationship.
