Windows 7: What can I do to add, subtract, etc in Calculator?

What can I do to add, subtract, etc in Calculator?

Hello!

I am using the calculator on my computer. Using the computer numerical keyboard, I can type in the numbers so that they appear on the calculator box on the computer screen. However I cannot use the signs for addition, subtraction, etc at all on the numerical keyboard. I can access everything by using the mouse on the calculator box on the computer screen; however this is very time-consuming. What can I do to add, subtract, etc? I have been able to do the successfully in the past.

I wonder if you might have a corrupted keyboard driver or if the keyboard itself is malfunctioning (Coke, Milk and OJ can mess it up real good sometimes

Check if the operation keys of your number block work in notepad.
If they work , try the aero calculator from here:
AeroCalculator by ~Solo-Dev on deviantART
If that one works your calculator file itself migh be corrupt.

Check to make sure that your numerical keypad/block is actually set to use numbers.

This is usually the key marked <Num> or <NumLock> Some laptops require that you use a function key.

Some keyboard remapping programs can disable various keys.

You have not entered your system specs, so there is no way of knowing what machine you are using.

Also, this is a BIOS feature on many boards if you want to have the numerical keypad activated at startup.

Some registry entries were also changed in Windows 7, so various "tweaks" for previous systems will not work.

Some more information;

mike, the + - etc keys should still work even without num-lock, at least on a standard non-laptop keyboard.

Indeed, but on some machines they don't. Also, I have no idea what machine he might be using.

well, the fact that the OP seems to be using the number keys successfully seems to indicate that num-lock is active anyway.

but then again, i could be wrong.

Many thanks for your suggestions. I had been trying the Num Lock key, but it made no difference. However I had my computer switched off for a few hours and when I switched it back on again, the calculator was working perfectly!

I have a Packard Bell PC using Windows 7 64 bit. I would have to do some digging to find out more technical information. This was not the first time that this problem had occurred.

Many thanks again!
