To round 814 to the nearest ten, look at the digit in the ones place, which is 4. Since 4 is less than 5, you keep the tens digit (1) the same and change the ones digit to 0. Thus, 814 rounded to the nearest ten is 810. Rounding can seem a bit tricky, but once you get the hang of it, it’s like riding a bike!
Rounding numbers has practical uses beyond just math class! It’s used in budgeting, sales tax calculations, or even estimating how much time you’ll need for a project. When we round, we simplify things, making it easier to understand approximate values and make quicker decisions. So next time you’re about to calculate, remember rounding is your friend!
