input takes a prompt string as its argument, which it will print automatically, but print returns None; it is this that gets printed by input. Your code is equivalent to:

prompt = print(...) # prompt == None
ans = int(input(prompt)) 

Instead, use str.format to build the prompt and pass it straight to input:

ans = int(input('{0}x{1}='.format(multi, num)))
