To summarize in Excel means to lay down the given numbers. For this there are different ways.

After "=" write through "+" the number that you want to add. At the end press "Enter". The cursor drops to the cell bottom or to the right, and the cell will affect the result of the addition. To view the numbers that you summarized, put the cursor on a cell. At the top below the toolbar there is a long line to the left of where it says "fx".
