=sum(1+1) it's a simple formula and won't change from any cells. Another you can do is to put a value in a specific cell, let's say, C3. Then have a formula that says, =sum(C3+2). But if you REALLY wanna impress someone - put a value in A1 - anything at all. Then put this formula in any other cell you want. If you change cells, you get a different answer. If you change the # in A1, you get different answers, all thanks to the RANDom function. =SUM((RAND()*100)+A1)

A variable that holds an address is known as a pointer variable.
Such variable "points" to location of memory in computer, the location can be another variable, primitive data type, object and more.
The answer is therefore B.
Hope this helps.
