Accumulating & Internalising Corporate Knowledge in the Modern Era 01

A kid is working on a math calculation, with the parent aside

Both quickly worked out the answers.

The math to be calculated is like this:

A frog 🐸 fell into a 10-meter-deep well.

Every day the frog can jump up 3 meters. Yet unfortunately, the wall inside the well is so slippery, that it slips back down by 2 meters.

Then how many days it will take, for the frog to get out of the well?

You think? 😉
