My Answer is:To make 1000, the ones digit has to add up to something ending in a zero. That's 40, which means "88888888" will need to be divided into 5 numbers.

When you add the ones digits to 40, you'll need to carry the 4 into the tens place. The tens place will also need to add to something ending in a zero to make 1000. With carrying the 4, you'll need two 8's to make 16.

Now you'll need to carry a 2; add an "8" to that, and you'll get 10, which looks a lot like the start of 1000. Let's see where we are - we need five numbers with a ones digit, two with a tens digit, and one with a hundreds digit. This gives us 888+88+8+8+8, or 1000!
