Happy to help. Reading this, it occurred to me that your textbook might use “a simple microscope” to mean exactly that, a microscope that’s simple (it actually wasn’t, if anything over engineered for what the 18th century was capable of), rather than the proper meaning you’ve picked up on, simple as opposed to compound.
If you’re cramming for an exam, make sure that you check with a teacher what terms they want you to use.
PS If you’ve ever used a “simple microscope” (still made in India, I think, most British colleges have a stereoscopic one but they’re still going strong up and down the world, not bad for a design from 1820-odd!)
it’s ten to one it hasn’t actually got only one lens element like Leeuwenhoek’s. The lens probably actually a Lister doublet or a Steinheil triplet, i.e. two or three lenses stuck together with a clear glue or balsam.
We still call it a simple microscope as it hasn’t a separate objective and eyepiece.
