Greater Than and Less Than

Sometimes you need to compare two numbers. Which one is bigger? Which one is smaller? The greater than and less than symbols help you show which number is more and which is less.

The Symbols

The greater than symbol looks like this: >. The less than symbol looks like this: <. The open end always faces the bigger number. Think of it as a hungry alligator that always eats the bigger number.

For example, 7 > 3 means 7 is greater than 3. And 2 < 9 means 2 is less than 9. There is also an equal sign = for when two numbers are the same.

Using Comparisons

Comparing numbers is useful in everyday life. You compare prices when shopping. You compare scores in games. You compare temperatures to decide what to wear.

You can also compare bigger numbers. For example, 1,500 > 1,200. Start by comparing the digits from left to right. The first digit that is different tells you which number is bigger.
