I added a table and then I added the days of the week and the different activities. To do a formula you have to go to the totals column and then you do the (=) equals sign, Then put in your numbers, and it should look like (=81+12) and then you can click out of the box and the answer will be right in front of your eyes in the box. I think I would do the spreadsheet for like how much money I spend on random things from amazon on a week or how many times I almost sleep in and miss zooms.
