Python Arithmetic

Addition

Adding in Python is very simple. To add numbers, we just put a plus (+) in between them.

Subtraction

Subtraction is the same as addition, but now using a dash (-).

Multiplication

Multiplication is also the same as addition, but using an asterisk (*).

Division

Adding in Python is very simple. To add numbers, we just put a slash (/) in between them.

Getting the Remainder

Let's say that we want to know the remainder of a ÷ b. In Python, we stick a percent symbol between a and b. So, a % b. In programming, this operation is called modulus.

Floor Division

Here, "floor" means "rouding down". This is basically like not doing the decimals in long division. Instead of using /, here we use //.

Exponents

Exponents are easy. If we wanted to do a^b, we would write it as a ** b in Python.
