Phi-3 Mini solving math problems step-by-step

I've been using Phi-3 Mini for my kids' homework help. The reasoning is impressive for a 3.8B model. It doesn't just give answers — it walks through each step clearly. Tested on algebra, fractions, and word problems. Pass rate vs GPT-4: about 78% on the same questions. That's wild for a 2.2GB model.
