Answer 1

179+29=178+(29+1)=178+30=208
4217+67=4214+(3+67)=4214+70=4284
534+48=532+(2+48)=532+50=582

Answer 2

179 + 29 = 208 4217 + 67 = 4284 534 + 48 = 582

To solve these addition problems, you can follow the associative property of addition, which states that the grouping of numbers being added does not affect the sum. In other words, you can add the numbers in any order and still get the same result.

Let's take the first example: 179 + 29. According to the associative property, we can group the numbers differently without changing the sum. So, we can rewrite it as (179 + 20) + 9. Now, we can add 179 and 20 to get 199, and then add 199 and 9 to get the final result, which is 208.

Similarly, for the second example: 4217 + 67. We can group it as (4210 + 7) + 60. Adding 4210 and 7 gives us 4217, and then adding 4217 and 60 gives us the final result, which is 4284.

Finally, for the third example: 534 + 48. We can group it as (530 + 4) + 40. Adding 530 and 4 gives us 534, and then adding 534 and 40 gives us the final result, which is 582.

So, by applying the associative property of addition, we can solve these addition problems.
