Why doesn't math work at the planck length?

The Planck length is the smallest known measurement humanity has seemed to be able to measure and define.

Since the Planck length is so minuscule, any mathematical operation you try to complete using this value would simply be like using 0.

Note: This is simply my educated opinion based on my own knowledge, but I hope this helps or at least sparks some interest.

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
