That’s a great way out..!! Thank so much for your quick responses… I will get back to this once I try this out!

For example, to calculate average of marks of n number of subjects, user will write down subject name in field A1 and marks in field B1. Then the user can click on more button to have the same fields as A2 and B2. After adding 5 subjects and marks for them, he can click on ‘submit and get average’ button to add B1 + .. + A5 and divide it by 5 with arithmetic equation and print the result.
I hope I explained it properly!

@webdesignerchristian Thank you for quick response! I have a clue now..!!
