The value of b must be 8
To add 26 and 17 using the common core method with mental math, you can break the numbers into tens and ones. First, add the tens: 20 (from 26) plus 10 (from 17) equals 30. Next, add the ones: 6 (from 26) plus 7 (from 17) equals 13. Finally, combine the two results: 30 plus 13 equals 43. Thus, 26 plus 17 equals 43.
