At the bottom-right corner of the cell, there will be a small, blue square. Hold the left-click button on your mouse and drag it down the column.

As you drag down the column, any unlocked cells will fill themselves in to the equation. This will quickly do the math for you, as you only need to fill in the equation once.

The main thing that you need to know is that the fill down function works by recognizing and fulfilling patterns it sees. For things like Dates, Numbers, and Weekdays, you will be able to sometimes turn as little as one cell into a statement for Google Sheets to fill out.

Dates: For dates, simply fill in the date in the normal way you would on any form (MM/DD/YY) or (DD/MM/YY) if you do that sort of thing.

Number: For numbers, the way I do it is I fill in the starting number along with the following number in the cell below.

You will also need to highlight both and then click and drag from the 2nd cells corner.

Day of the Week: For listing days of the week, you can simply write down the day of the week or even its abbreviation (Mon, Tues, Wed, etc.). When you autofill dates, google sheets is able to detect those patterns and fill the rest of the dates out for you.

Step #2: Verify
