Technique of Using New Spreadsheet software Problem: Prepare a marksheet for Kamal Roll:102 who scored 70 in Bangla, 80 in English, 90 in Math, 85 in G.Sc, and 45 in ICT. Also calculate total marks. Solution: Step-1:Open a new worksheet Step-2: Click on A1 cell and Type Name Step3: Click on B1 cell and type Kamal Step-4: Click on A2 cell and type Roll Step-5: Click on B2 cell and type 102 Step-6: Click on A3 cell and type Bangla, on A4 cell type English, on A5 cell type Math, on A6 cell type G.Sc and on A7 cell type ICT

Continued from prev. slide Problem: Prepare a marksheet for Kamal Roll:102 who scored 70 in Bangla, 80 in English, 90 in Math, 85 in G.Sc, and 45 in ICT. Also calculate total marks. Continued from prev. slide Step-7 Click on B3 cell and type 70, on B4 cell type 80, on B5 cell type 90, on B6 cell type 85 and on B7 cell type 45 Step-8: Click on A8 cell and Type Total Step-9: Click on B8 cell and type =sum(B3:B7) and press enter Step-10: So Total 370 will be displayed on B8 cell. We can also type=B3+B4+B5+B6+B7 to calculate total marks
