Let's try to solve a simple problem in Scala - Calculation of the simple interest.

We want to calculate what would be the simple interest for 5 years if the principal amount is 500 and the interest rate is 12% annually.

We will need to define 3 variables and perform the calculation to get the interest.

Open Jupyter notebook on the right-hand side tab.

Declare integer variables as described below.

`principal`

- assign a value of 500`interest_rate`

- assign a value of 12`years`

- assign a value of 5Now, declare a new variable

`interest`

which will be assigned the value of calculation of interest like below:`interest`

= [calculation of simple interest using above defined variables]Press Shift+Enter in each of the cells where you wrote the code.
