Kyle is searching for the solver function but cannot seem to find it anywhere, not even under the Data tab in the ribbon.

Where can it be found?

If it is not on the ribbon, it has not been activated
Kyle needs to activate it under Add-Ins in the Excel Options dialog box.
It is not under the Data tab because it is a formula
Kyle needs to look under the Formula tab on the ribbon in the Add-Ins group.
It is not a function that is usually displayed on the ribbon
Kyle can add it to the ribbon as a macro function.
Solver is a separate program
Kyle needs to launch it from his operating system's Start menu.
