                     To create a program in MakeCode Arcade to display a square of numbers from 1 to 10

                   Concept: Square is when a number is multiplied by itself. For example square of 5 is 25, (5x5=25).
                   To perform the task, follow these steps:

                   Step 1:  Visit the link: https://arcade.makecode.com/. Click on ‘New Project’, Write the name of
                            your project ‘Square’, and then click on ‘Create’.
                   Step 2:  Click on ‘Variables’, select ‘Make a variable...’, write the name of the variable as ‘a’, then
                            click on ‘OK’. Variable ‘a’ will appear in ‘Make a Variable…’.

                   Step 3:   Select the ‘Change a by 1’ block, it will appear on workspace, drop it to ‘on start’ block.
