wouldn't it be 99999 and 11111?
To find the number sentence with the greatest sum, we want to maximize the digits in each box. The largest digit available is 9, so we should use 9 in each box, resulting in the number sentence:
9 9 9 + 9 9 9
To find the number sentence with the least sum, we want to minimize the digits in each box. The smallest digit available is 1, so we should use 1 in each box, resulting in the number sentence:
1 1 1 + 1 1 1
