What is the Finance theme?
The Finance theme uses equations styled after common business math: revenue minus cost, margins, markups, pricing calculations. The equations use standard Nerdle operators, but the number patterns feel like real-world financial arithmetic.
It's 8-column, unlimited play. The numbers tend to be in ranges you'd see on a price tag or invoice: amounts like 50, 75, 99. If you deal with numbers at work, this theme will feel more familiar than abstract math.
