Why These Help
Estimating before calculating (Q1) builds the habit the chapter specifically teaches — a quick sanity check that catches regrouping mistakes before they go unnoticed.
Frequently Asked Questions
Are these questions taken from the NCERT textbook?
No — original practice questions using the same travel-budget style problems from the chapter.
Why does estimating first help even when you calculate the exact answer anyway?
It gives an expected range for the answer, so if the exact calculation comes out very different, you know immediately to recheck your work.
