Why would you get a positive OPK strip test but a negative on the Clear Blue Digital OPK with same urine sample?

The reason you could get a posative from one brand of Oops test and a negative with another. Even if you use the same sample, the sensitivities of the different brand tests vairy.

On Monday I did two clear-blue tests faint but positive today did digital clear-blue which says not pregnant?
If you got a positive you are pregnant. These is no such thing as a false positive. Another pregnancy test may give you a negative because it requires a larger amount of HCG to be detected before it will read positive. This is especially true for digital tests. So, congratualations.
What does the inside strip of a clear blue digital pregnancy test look like when it's positive?
The digital pregnancy tests are the same set up as the basic tests. You will urinate on the test (or dip it in your fresh urine) and it will say positive or negative, but if you were to take the test apart the inside has the strip that will show with the one (if negative) or two (if positive) lines. From my experience, sometimes the test will display a negative reading but the strip will be positive with a faint line so always double test a few days later.
If your first urine samle was positive can a split urine sample come up negative?
It depends on how the first sample was tested. If the first half was tested on a dipstick test and you KNOW you haven't been doing drugs--say, you're taking naproxen sodium for knee pain and you come up positive for marijuana (naproxen cross-reacts with the THC test), testing the split sample with GC/MS should clear you. OTOH, if you smoke weed and your first sample came up positive on GC/MS, assume the split sample will also be positive.

Does a negative and positive equal a negative?
If you have a negative and a positive, then all you have is a negative and a positive. If you want to talk about performing some arithmetic operation on a pair of numbers where each number has one of those signs, we can certainly discuss that. But you'll need to be much more clear in your question. A great start would be to specify which arithmetic operation you're interested in, and we can go from there.

What colors do gram-positive and gram-negative bacteria stain?
Gram positive are purple. Just remember Positive+Purple. Gram negative are a reddish color from the safranin. After using the crystal violet, the grams iodine acts as a mordant to hold color on cell wall. When using the alcohol, the gram positive will stay purple while the gram negative will become clear. This is due to the outer cell wall of the gram negative specimen (lipopolysaccharide) basically being stripped by the alcohol, so now you have a clear specimen again. When you add the safranin it sticks to the gram negative cell wall, hince the red/pink color.
