Now we will start to learn different formulas.
At times, we need to do addition to figure out the desired result. The very basic way of doing is: =С2+С3+С4+… But this method is cumbersome and tedious if computation involves large sets of data. But we will use the SUM function.
=SUM(H4:H8) - this will return sum of H4+H5+H6+H7+H8.

**Your task is to calculate the total revenue for all months (Put this formula in cell C4).**
