My friend is trying to find the surface area of something on a flat surface. The problem is that we are dealing on the microscopic level so obviously the numbers are less than one.

Lets say it was 2x2. We could say that the area is 4. But when we are dealing with a number less than one the area gets smaller, so what the hell are we doing wrong?

You're not doing anything wrong. Think about if you have a square that is one inch by one inch. The area of that square is one square inch. So if you divide that square by two on each axis then you have a square that is 1/2 inch by 1/2 inch. The area of that square would be .5 x .5 = .25 square inches. Meaning four of those would add up to the original square. Make sense? It might seem off, but it is still right.

It still works. Just carry on as usual.

The following square's shaded region is 25% of the total area, obtained from halving the length of the sides of the original square.

Let the math do the thinking for you.

you need to divide instead of multiplying when you're dealing with numbers less than one.

for example, if you do 0.5 x 0.5, the answer your calculator will give you is 0.25.
if you divide instead the answer will be 1.

I can't believe this thread was made.

the real answer is divide by 0 until you get the answer.
