In Excel, the F2 key allows you to edit within a cell. Select a cell and press F2 to begin editing the cell contents. If F2 does not work for you, check your keyboard, the F2 key may not be active. Many keyboards have multiple functions for keys, as indicated by something printed on the top and on the front of the key.

they are known as the function keys.
The F Lock on a keyboard disables the use of function keys. E.G: F1 F2 F3 etc.
I'm not sure I really understand the question. If you have two functions, F1 and F2, then by definition of function you have: If X=Y then F(x)=F(y) for both F1 and F2 (F1+F2)(x) is defined as F1(X) + F2(X), and for every X there exists a unique F1(x) and F(2)(x) and the sum of these two numbers is obviously unique. If the question meant that the range of F1 and F2 were included in Z and how do you show that the range of F1 + F2 is also a subset of Z, then it's as simple as: the sum of two integers is an integer. and for the second part: the product of two integers is an integer.
