It sounds like you are using a laptop (always best to explain the computer type, it makes help easier)
The problems you describe simply indicate that "Numlock" is acive for the keyboard, where those keys are dula use as a number pad.
Without knowing the hardware the best I can suggest it that you use the Fn key plus F5 or whatever the assigned key is to toggle the Numlock function.
