Question

when you multiply a three-digit number by a four-digit number, what is the greatest number of digits the product can have? Explain

Answer 1

7 digits

Explanation:

When we multiply a two digit number like 17 by another 2 digit

The highest number of digits we can get as answer is 4 digits

This can be seen in the case of 10 * 10

So what this mean is that at any point in time, we can sum the numbers to get the digits

3 + 4 will give 7

And that is the greatest number we can get
