Using the link below 

lets create the algorithm  (using English) and then the flow chart shown in the video

Are you confident in creating a flow chart

😒🙁😐🙂😃

Example 1: 10 plus 20 using an algorithm

Algorithm in simple English

1. sum = 0(process)

2. Enter the numbers (i/o)

Add and store the results (process)

Print sum
