Looking for something with all the formula's on it...
Found another post like this but most links were dead except this one.
Which I can't zoom and cant view the back, so I am guessing it doesn't have the formulas I would like to have on it.
I found another one online for 10$ that has most of what i want on it. Still I figured u folks would know best.
What do u use/prefer?
Please add a link if possible.
