📚 Topic Summary
Understanding place value is crucial for working with whole numbers. Each digit in a number has a specific place value, which determines its contribution to the overall value of the number. Starting from the right, we have the ones place, tens place, hundreds place, thousands place, and so on. When we work with numbers up to the billions, we extend this concept further, including places like ten thousands, hundred thousands, millions, ten millions, and hundred millions, finally reaching the billions place. Mastering place value helps us read, write, compare, and perform operations with large numbers accurately.
