### Operations in python

Just like a calculator, python works well with numbers. You can add variables together if they are the same type!

There are a multitude of other mathematical functions that you can use.

• `*` = Multiplication

• Can be used with floats and integers
• `+` = Addition

• Can be used with floats, integers and strings
• `-` = Subtraction

• Can be used with floats and integers
• `/` = Division

• Can be used with floats and integers

#### Other functions:

• `**` = Exponential

• `//` Integer Division

• Integer division is division in which the fractional part (remainder) is discarded is called integer division.
• `%` Modulus Division

• In computing, the modulo operation finds the remainder after division of one number by another (sometimes called modulus)

## Examples in the interpreter!

```
```
# Declare variables x and y
x = 2
y = 3

# Add x and y and print the result
print('The sum of x and y is: ',x + y)

# Subtract x and y and print the result
print('The difference of x and y is: ', x - y)

# Multiply x and y and print the result
print('x * y equals: ', x * y)

# Divide x and y and print the result
print('x / y = ', x / y)
```

```
