1.Order amoxicillin 1000 mg p.o.t.i.d.

Available amoxicillin 500 mg tables how many tablets will you administer per dose?

I did the math 500/1000=2 per dose or 4 per dose?

You should be able to do this in your head in a nanosecond without complicating it by setting it up.

Doc over stock. So write what is ordered divided by what is on hand. Just a catchy way to remember it.

Is it not clear that if 1 tablet has 500 mg, it takes 2 tablets to yield 1000 mg?

You could think about this in terms of proportions...

The preceding reads as, "if 1 tablet equals 500 mg, how many equal 1000 mg?"

It is simply algebra to isolate the variable "x" by multiplying both sides of the equation by "1000 mg"
