You might be unaware of the fact that there's no shortcut key by default for PC
It was quite a shock for me too as the calculator is one of the very basic needs while you're working, so after rigorous research, I found a simple way to get a shortcut key. You can assign shortcuts as per your choice but I'll be specifying it as "Ctrl+Alt+C", this method is applicable only for Windows.
Right-click on your desktop and create a shortcut.
The location of the calculator is the same for everyone, so you can directly copy this and paste it in the space provided, "%WinDir%\System32\calc.exe", then click on "Next".
Now you can give this a name as per your choice, but you should name it "Calculator" as it's a calculator.
Then hit finish, this process was done for creating the calculator shortcut on "Desktop". Now we've to assign it a key that we'll be using as a shortcut to directly open the Calculator.
Now right-click on the calculator icon and go to properties.
Under Calculator properties go to the "Shortcut" tab and bring your mouse to the "Shorcut key" space provided, the cursor blinks as if you can type the shortcut key but you can't, you simply have to press the alphabet you wish your shortcut to be, say, "C", then it'll automatically add "Ctrl+Alt" with it. Just hit the alphabet.
Now click on "Apply" then OK and you're good to go. Now as you hit this shortcut you'll get a calculator popped right in front of you.
Tip: If you delete the calculator icon from your desktop the shortcut will no longer work, so make sure to not delete it or create the calculator shortcut in some other folder
