3) Explain the commonalities and differences between functions and formulas.

4)  Explain how should we calculate (5/5)*4/ (3-3*(3*6)) using Excel’s order of operations.

5) Suppose that cell A1=1, B1=2 and C1=3, and in Cell A4 we type SUM (A1:C1) and in Cell A5 we type =A1+B1+C1, are the values in Cell A4 and A5 equal? If not explain why.

6) Suppose that Cell A1=1, B1=2 and C1=3 and D1 is blank, In Cell A2 we type =COUNT (A1:D1), what is the output of the function? Explain briefly.

7) Suppose that Cell A1=1, B1=2 and C1=3 and D1=4, in cell A2 we type =SUM (SUM(A1:B1),AVERAGE(C1:D1)). Write an equivalent formula for the function and calculate the result.

8) Can we use a function in a formula? Justify your answer with an example.

9) Can we use a formula as an argument of a function? Justify your answer with an example.

10) Suppose that Cell A1=1, B1=2 and C1=3 and D1 is blank, in cell A2 we type =AVERAGE(SUM(COUNT(B1:D1),AVERAGE(A1:D1)),COUNT(A1:D1)). Explain your approach (steps) to find the return value of the function.
