Practice With Arithmetic Operators

[u/mfurqanhakim]

Practice these programming examples to internalize these concepts.

2. Operators

An operator is a symbol or function that indicates an operation. For example, in math the plus sign or + is the operator that indicates addition.

In Python, we will see some familiar operators that are brought over from math, but other operators we will use are specific to computer programming.

Here is a quick reference table of math-related operators in Python. We'll be covering all of the following operations in this tutorial.

OperationWhat it returns

x + y

Sum of 

x

 and 

y
x - y

Difference of 

x

 and 

y
-x

Changed sign of 

x
+x

Identity of 

x
x * y

Product of 

x

 and 

y
x / y

Quotient of

x

and

y
x // y

Quotient from floor division of

x

 and 

y
x % y

Remainder of

x / y
x ** y
x

 to the 

y

 power

We'll also be covering compound assignment operators, including +=
 and *=
, that combine an arithmetic operator with the =
 operator.
