I use just 4. But I follow the typing conventions like which letter to type with left hand or right hand.

Nine.  I don't use my left thumb.  My right one presses the space key.

If they use the standard keyboard layout, the Eastern languages usually just use multiple key presses to generate characters, instead of having individual keys for each.  Most businesses use the standard QWERTY layout, and simply use function buttons (or ALT, CTRL combinations) to generate needed symbols and characters.  You can buy a ton of different keyboards that have other than US standard symbols imprinted on the keys along with the normal characters. You can also find overlays that cna be used with the standard keyboard..

3 - The numbers on the right are the numbers of letters it takes to spell the number on the left.

look at the keyboard... do you see the >?  now hold down the shift button and press that one at the same time.  do it again to get another one.  then look for the : on the keyboard.  hold down the shift button and then press the : at the same time.  do the same for the ?.  does that help?

It doesn't matter one way or the other if you don't have to recite it somewhere. Just be consistent and read for the letters. The first one is correct.

No, but you can work it out on paper. I know because I did it once. You have five letters, so there should be 25 combinations, Of course, as two letters are the same that would make it 20. I think. Just give it a go. It's always more fun to work these tings out yourself.

My personal preference is print.  English is my mothertounge, but my cursive style is almost illegible, plus, I can print a lot faster than I can do cursive. \n\nI have found that most of the engineers at my workplace use print for legibility's sake.

I second that! Should someone start a petition? I think there should be a new category for people who intend to capitalize the first letter of a sentence and use punctuation. I know the "shift" key is way over on the left side of the keyboard, but I cannot bring myself to believe that everyone on Yahoo! Answers has stubby fingers that can't reach it.

I'm left handed too but I use both depending on the situation.  If i sit next to a right handed person who is to my left, then i use my right so i am not bumping into them
