Large numbers are values that are significantly greater than what we typically encounter in daily life. They are often used in fields like mathematics, science, and finance to represent quantities such as populations, distances, or financial figures. For example, the number 1,000,000 represents one million, which is a common large number used to describe populations of cities or countries. Understanding large numbers can be challenging because they can be difficult to visualize. To help, scientists and mathematicians often use scientific notation, which expresses large numbers in a more manageable form. For instance, 1,000,000 can be written as 1 x 10^6, making it easier to work with in calculations and comparisons.
