Question about Casio Office Equipment & Supplies
Can someone tell me how to change the battery on a Casio D-20M calculator please?
Turn calculator over. Look for some small screws. Loosen them, remove the cover. Notice how the two batteries look when they are in place (polarity) and replace them. Close the cover and tighten the screws again. You need two LR 44 batteries or equivalent.

Like you maybe know in math (I know!) log x base y = log x / log y
so what you need its just input your number (x for example) and log it, than divide log x by log 2.
just: log x / log 2. (by the way in calculator the meaning of log x is log x base 10 the default base is 10)

Testimonial: "Many thanks. A simple task but without the instructions, difficult. I have saved the instructions so when vat goes back to 17.5% I can change it back."
