[TYPO] Operating Systems - IO Management

What needs to be fixed?
"The whole operation will take 1 CPU access to the command register and then 188 - 1500 / 8 rounded up - accesses to the data register."

I think the use of '-' is supposed to suggest an aside in the sentence. When I first read it, though, I was confused, because "188 - 1500" can be read as a mathematical operation.

Instead, I would suggest writing it as, "The whole operation will take 1 CPU access to the command register and then 188 (calculating 1500/8 and rounding up) accesses to the data register."
