Answer 1

Answer:

hey mate here is your answer

Step-by-step explanation:

What is the sum of the first 100 whole numbers? 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.
