Large Numbers Around Us
Populations of countries, distances to stars and government budgets all run into lakhs, crores and millions. This topic in the Class 7 mathematics syllabus trains you to read, write and compare such large numbers with confidence in both the Indian and International place-value systems. You will practise ordering them, rounding them to sensible estimates, and performing addition, subtraction, multiplication and division on them. Word problems drawn from census figures, distances and prices show why place value and estimation matter in real life.
