How to Estimate a Math Problem

How Can I Estimate a Math Problem?

Estimation is a great way to check your work and solve math problems quickly. When you estimate math problems, start by rounding off the numbers. Rounding makes math problems easier to estimate.

First you need to decide what number to round to. If you're working with decimals, you might want to round to the nearest whole number (5.7 rounds to 6). If you're working with whole numbers, round to the number nearest your original number as possble. Close rounding will make your estimation more accurate. If you round to the nearest ten, your estimation will be more accurate than if you round to the nearest thousand.

For example, if you round 4517 to 4520 (nearest ten), your estimation will be more accurate than if you round to 4500 (nearest hundred).

Once you've rounded the numbers, you can estimate the answer in your head.

Here's an example of how to estimate a math problem.

51 X 69 = ? This is a really hard problem to do in your head. Start by rounding to the nearest ten.

51 rounds to 50 and 69 rounds to 70.

50 X 70 isn't that hard to do in your head. Multiply 5 X 7= 35 and add two zeros to your answer.

50 X 70 = 3500

Now you know that 51 X 69 is about 3500.

If you do the math, you'll see that 51 X 69 = 3519. That's only 19 off. Not bad for a quick estimation.
