## How To Add 3 Numbers Together

There are a number of different ways for you to approach solving problems that have more than a pair of values. Here are a few methods to consider:

• 1. Sequential addition – Simply add the first two numbers together, and then add the result to the third number.
• Example: 4 + 5 + 3 First, add 4 + 5 = 9 Next, add 9 + 3 = 12
• 2. Grouping – Group numbers in a way that makes it easier to add them. This is especially helpful when you can create sums that are multiples of 10 or when working with larger numbers.
• Example: 18 + 2 + 12 First, group 18 + 2 = 20 Next, add 20 + 12 = 32
• 3. Associative Property – The associative property states that the grouping of numbers in addition does not affect the sum. You can use this property to rearrange the numbers to make the addition process simpler.
• Example: 6 + 4 + 7 First, rearrange to 4 + 6 + 7 Next, group 4 + 6 = 10 Finally, add 10 + 7 = 17
• 4. Place value method – Break down the numbers into their place values (ones, tens, hundreds, etc.) and add them separately. Then, combine the sums to get the final result.
• Example: 23 + 45 + 12 First, add the ones place: 3 + 5 + 2 = 10 Next, add the tens place: 20 + 40 + 10 = 70 Finally, combine the sums: 70 + 10 = 80

Choose the method that works best for you or the specific problem you’re trying to solve. With practice, you’ll develop a sense of which strategy to apply in different situations.
