**Python Basics Tutorial 3 – Python Math Expression**

### Notes from the video ‘**Python Course Singapore | Learn Python Programming |Python Tutorial 3 – Python Math Expression’:**

The programming term for calculation is **math expression**.

The common operators in math expression are:

**addition**, which is represented by the plus sign (+),**subtraction**, which is represented by the minus sign (-),**multiplication**which is represented by the asterisks sign (*),**division**which is represented by the forward slash (/) and**exponentiation**which is represented by two asterisks signs (**)

**Now, let’s try out a few examples.**

Let’s try printing 2 times 5. This displays **10** on the screen.

Next, let’s try printing 50 divided by 2. This displays **25** on the screen.

Now, let’s try assigning math expression to variables instead.

randomNumber = 10 – 5

anotherRandomNumber = 5**2

sum = randomNumber + anotherRandomNumber

In the statements above, the variable **randomNumber** is assigned the result of 10 minus 5 which is 5 while the variable **anotherRandomNumber** is assigned the result of 5 to the power of 2 which is **25**.

The variable **sum** is the sum of the two variables **randomNumber** and **anotherRandomNumber** which is 5 plus 25 and it should give us **30**.

Let’s see if it’s correct by printing the variable **sum**.

And yes, we got **30**!
