1. Dear Team

Your description is pretty comprehensive and clear :D

Under "Approximation and Estimation", please suggest when you would use the skills learnt here? Under what situation/circumstances you would suggest we use this skill/knowledge and when we should not apply such skills?

Please elaborate in the same post.

Cheers!
