Answer:
5050
Explanation:
Gauss noticed that if he was to split the numbers into two groups (1 to 50 and 51 to 100), he could add them together vertically to get a sum of 101. Gauss realized then that his final total would be 50(101) = 5050

Answer:
55 + n = 100
55 + n = 100
n = 100 - 55
therefore,
n = 45
