### Why do we round or estimate numbers in real life?

The reasons why we round or estimate numbers in real life are so numerous. In the first place, you’ll recall that although these numbers when rounded up or down are slightly less accurate, their values are still relatively close to the original value.

That notwithstanding, rounded numbers is the key skill you need to quickly estimate, compare or order numbers, money amounts, sums, measurements etc. in real life and in the math class.

As earlier said, we round, compare, estimate and order numbers on regular basis and in many different real life situations. For instance, estimating time, rounding the prices of items to the nearest money amounts. Here, you can easily determine if you have enough money to buy everything on your market list.
