He defines maths as a four step process:

**1. Posing the right question:** The first step is to ask the right question.**2. Real world —> Math formulation:** Take the problem and turn it from a real world problem into a math problem**3. Computation:** Turn it from that into some answer in mathematical form**4. Math formulation —> Real world & Verification:** Turn it back from mathematical solution to real world.

He mentions that an alarmingly high rate (80%) of time spent on teaching maths is spent on Step 3: Computation, and that too – manual. The philosophy is simple: Repeated practice will make one understand the procedure better. However, that’s the one step that a computer can do better. So, why not use computers to do that step and focus on the remaining three?
