# Less Than vs. Equal To: Improve Math Vocabulary

In mathematics, the concepts of less than vs. equal to are foundational for understanding numerical relationships and inequalities. Understanding the exact meaning and proper usage of these symbols is crucial because even a small misinterpretation can completely change the meaning of a mathematical expression.

## The Difference between Less than and Equal to

### Key Takeaways

• Less than (<): This symbol indicates that one number is smaller than another. For example, if we say 3 < 5, we mean that 3 is less than 5.
• Equal to (=): The equality symbol shows that two values are the same. So when we express that 4 = 4, it’s clear that both sides of the equation represent the identical value.

### Less than vs. Equal to: the Definition

What Does Less than Mean?

“Less than” is a term we use when one value is smaller than another. In mathematics, we use the symbol < to denote this relationship. For instance, if we say 3 < 5, we’re asserting that 3 is less than 5. Here’s another example: if there are 2 apples and 6 oranges, we express that with 2 < 6, indicating fewer apples than oranges.

What Does Equal to Mean?

“Equal to” indicates that two values are exactly the same. We signify this with the symbol =. For example, if we have two groups of marbles and each contains exactly 4 marbles, we write this as 4 = 4. Similarly, if a recipe calls for 2 cups of sugar and you measure out precisely 2 cups, you have 2 cups equal to the required amount, represented by 2 = 2.

### Tips to Remember the Difference

1. L Method: Remember that “less than” starts with an “L”; similarly, the symbol “<” resembles an “L”. Hence, “<” means “less than”.
2. Equal Sign Recall: Notice that the equals sign ” = ” consists of two parallel lines. Since the lines are the same length, they symbolize the concept of things being the same, or equal.

## Less than vs. Equal to: Examples

### Usage and Examples

Here are some real-life scenarios to demonstrate:

1. Age Restrictions: If a ride requires you to be under 12 years of age, we write that as age < 12.
2. Budget Limits: If our budget for a project is up to \$500, we denote this as budget ≤ \$500.
3. Temperature Thresholds: Saying that water freezes at 0 degrees Celsius or lower is written as temperature ≤ 0°C.
Comparison Type Symbol Example Interpretation
Less than < 3 < 4 3 is less than 4
Less than or equal to 7 ≤ 7 7 is equal to 7 (hence, ≤ 7)

### Example Sentences Using Less than

### Example Sentences Using Equal to

## Related Confused Math Terms

### Less than vs. Fewer than

Less than” is typically used for quantities that can’t be counted individually, known as uncountable nouns. On the other hand, “fewer than” is correct when referring to countable nouns.

Example sentence:

• We used less than a gallon of paint to cover the wall.
• We had fewer than twenty participants in the survey.

### Equal to vs. Equivalent to

Equal to” conveys that two quantities are the same in number, amount, or degree, often used in mathematics or when comparing measurable attributes. “Equivalent to” implies that two entities are comparable in value or function, even if they aren’t the exact same thing.

• The number of apples in this basket is equal to the number in that basket.
• Our online subscription service is equivalent to accessing a large library.
