my 3rd laboratory

I continued working in Excel. I have learnt how to define a range of cells. For eg. if we write A3:C3 it will take every cell from A3 to C3 (A3, B3, C3) and when we take A1:C3 we will have (A1, A2, A3, B1, B2, B3, C1, C2, C3). Than I have exercised to work with formulas such as SUM. After that I spoke with my coleg about our project.
