Also about computing

 So when to work with I said is good choice a computer the numpad in the keyboard also the numpad could bought and conected to the laptop I never tried but probably works, also is good about the mouse that in my city is the only kind of mouse is have 3 buttons, have mouses that only have the left button and the right button but don't have the middle button on the mouse, that is a scroll wheal that also you push, pushing down the scroll wheal(the middle mouse button - the mmb of the mouse), is that are references books that say rmb - the right button, lmb - left. But if you don't work in virtual 3d enviroment the 3rd button you use to scroll a page, in the 3d is to zoom and move inside the 3d enviroment. Rute Bezerra de Menezes Gondim
