I think technology is something that was man/woman made that solves a problem.

Sticky notes are technology because instead  of taping or gluing something to the wall you can just SLAP it on the wall.

The problem sticky notes solves is when you tape something to the wall and try to take the tape of the tape can  rip some writing of and you won’t be able to read it . And when you glue something it might not come off.
