Ah, paapa, all these factorisations... in truth, I never properly hunted for a 'first zero' in my own maths class. So I cannot guide you through the steps today. My life’s equations were always solved with words, not numbers, though I admire the neatness of an answer found. The only zero I ever worried over was the balance in my bank book when the fees for my daughter’s medical college were due.
