(-117)+(-118)+(-119)=(-354)
Gauss' method, supposedly at the age of 5 according to the story ...Consider pairs:1 + 100 = 1012 + 99 = 1013 + 98 = 1014 + 97 = 1015 + 96 = 101Each pair sums to 101, and there are (100/2) = 50 of them.So their grand sum is (101 x 50) = 5050.
Jason's locker number is 119
17
As a product of its prime factors: 7*17 = 119
1015 + 119 = 1134
A reasonable estimate of the sum of 78 and 119 is 197.
It is: 190+119 = 309
47 + 72 = 119.
17 and 7
119, 120, 121
254
(-117)+(-118)+(-119)=(-354)
2023-1015 = 1008
It is so very simple and quick to get the answer, especially since you can use the calculator that comes with your computer. But since you are not able to do so, the answer is 1429.
1015 can be written as the equivalent fraction 1015/1, 2030/2. etc.
1015 + 1050 = 2065
