By default, Soulver displays a total of all your lines in the bottom right hand corner.
In many cases, you can simply paste in a set of lines from the internet and get an instant total.
You can also show the average of your lines by right-clicking on the total and choosing Switch to Average
Various units will be summed together if possible, with the larger unit used for formatting the answer.
If the total is not helpful in your particular workflow, you can hide it by hovering over it and clicking Hide

Press ⌘T or hover over an answer and click the make subtotal button (the middle button) to make a line a subtotal. A subtotal line will add up all lines above, up to the next subtotal or heading (#).
