Wolfe, I can see why you crossed out “sum”, given I was repeating it with “total”, but why did you remove the “of”?

The following five lines are my tightened versions, and to be honest I don’t know which is best... Although I do like the first and fourth ones.

We equal the sum of our memories.

We equal the total of our memories.

We equal the whole of our memories.

We equal our entire memories.

We equal our whole memories.
