This is a fair comment. I was looking at (delta assets), (delta liabilities).
(Edit:
The simplest thing is to consider a simplified accounting equation that says assets = liabilities. If I wanted to buy a house but had no personal worth, how would I afford it? Debt. The house would be the asset, the liability would be the debt.)
That's a non-equation, of course. Assets and liabilities are in dollars and net income is in dollars-per-unit-time.
Naturally, any conclusion arising from algebraic rearrangement of that non-equation will also be non-sensical.
