# How to check if a number is multiple of 10 in Python

In this tutorial, we are going to learn about how to check if a given number is multiple of 10 or not in Python.

Consider, we have a following number:

`a = 100`

To find if a above number `100`

is a multiple of 10 the number should be divided by 10 and the remainder is `0`

.

## Using % Modulo operator

To check if a number is multiple of 10 or not, we can use the `%`

modulo operator in Python.

The modulo `%`

operator returns the remainder of two numbers `100 % 10`

, so if we get a remainder `0`

then the given number is a multiple of 10.

Here is an example:

```
a = 100
if a % 10 == 0 :
print("a is multiple of 10")
else:
print("a is not a muliple of 10")
```

Output:

`"a is multiple of 10"`

In the above code we have added `a % 10 == 0`

in if condition, so 100 is divided by 10 and returns the remainder 0 then it prints the output “a is multiple of 10”.

Example 2 :

```
b = 300
if b % 10 == 0 :
print("b is multiple of 10")
else:
print("b is not a muliple of 10")
```

Output:

`"b is multiple of 10"`

## Checking if a number is not a multiple of 10

To check if a number is not a multiple of 10, we can use the modulo operator `%`

but the remainder of first number by second number is not equal to 0.

Here is an example:

```
if (23 % 10 != 0):
print ("23 is not a multiple of 10")
```

In the above code, 23 is divided by 10 and returns the remainder 3. So the given number is not a multiple of 10.
