I believe the numbers denote the number of grains of "sand" per square inch.
This number refers to the level of "grit". Therefore a 50 grit patch of sandpaper is rough and a 200 grit patch is much smoother.
The serial numbers on the back of a watch are there for the customer to know that the watch is real. The serial numbers can be looked up at the retailers.
you cross the numbers out from back to front
Egyptians made all the numbers back in B.C.

This is the three numbers located on the back of the card by your signature.
The numbers on the back of sandpaper refer to the grit size, which indicates the coarseness or fineness of the abrasive particles on the paper. Lower numbers indicate coarser grits, suitable for heavy material removal, while higher numbers denote finer grits, ideal for smoother finishes.
Yes
To sharpen a knife using sandpaper, start by securing the sandpaper on a flat surface. Then, hold the knife at a 20-degree angle and slide it back and forth across the sandpaper in a smooth motion. Repeat this process on both sides of the blade until the knife is sharp. Remember to use a fine-grit sandpaper for best results.
Coarse sandpaper has lower grit numbers, typically ranging from 40 to 60 grit. It is used for heavy material removal and rough sanding tasks where a smooth finish is not required.
The rougher the sandpaper, the more it takes off the material being sanded. The finer the grade (smoother) the smoother the finish will be. Rougher grades are used at the beginning to remove tool marks and shape the material, and you gradually work up to the finer grades for finish work. The very finest grades are used to polish the finish.
Sandpaper gets warmer when rubbed against wood due to friction.
The wood changes color
The Chinese were the first to use sandpaper, dating back to the 13th century. They would glue crushed shells and sand to parchment to create an abrasive surface for smoothing wood.
Sharkskin was originally used as Sandpaper. When modern manufacturing techniques came, sandpaper was mass produced.
Sandpaper is both helpful and harmful.
