Write a program to take two integers as input and output their sum. Both cases

Question

I used this to solve case 1:
a=6
a+=3
print(a)

When I write both cases in the same page, it makes me fail both.

I also tried this the first time:
a=int(input(6))
b=int(input(3))
c=(a+b)
print(c)

And it didn't work. It still results in strings and the result is 63 or 639 sometimes.

Answer 1

In code coaches, just use input()
instead if input(6) input(3).......

Answer 2

Thanks @Jayakrishna🇮🇳. That method solved them both.
