Final answer:
To find the sum, add the numbers together. To find the difference, subtract the smaller numbers from the larger numbers.
Step-by-step explanation:
To find the sum of 147, 167, 204, and 107, simply add the numbers together:
147 + 167 + 204 + 107 = 625
To find the difference, subtract the smaller numbers from the larger numbers:
204 - 147 = 57
167 - 107 = 60
Therefore, the sum is 625 and the differences are 57 and 60.
