# Compare numbers (up to 90000)

Lesson

### Up to 5 digits

Here we will find out whether a number is the same as, smaller than, or bigger than another number. To compare numbers we use certain signs.

 = When two numbers are equal or the same, we can use the equals sign. Example: 2 + 2 = 4 or 4 = 4 < When one number is smaller than another, we use the "less than" sign. Example: 3 < 5 (The number 3 is less than the number 5) > When one number is bigger than another, we use the "greater than" sign. Example: 9 > 4 (The number 9 is greater than the number 4)

If we look at the "less than" and "greater than" signs they look like the letter V turned around. An easy way to remember the correct way to write the signs is to remember that the small end always points to the small number.

Once we have compared numbers, we can order and arrange them in ascending and descending order which we have already looked at in Ordering Numbers.
