The answer is vague but correct . Take any prime number and any other number whose combined digit length is 401 and their product will generate a 400 or a 401 digit number.
It is 400, exactly as in the question. A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right.

200*200=400 200+200=400
Yes.
400/4= 100 and 800/4=200
Either 4000, 400, 70 or 6.
