A reasonable estimate of the sum of 78 and 119 is 197.
It is: 190+119 = 309
47 + 72 = 119.
119, 120, 121
The sum of three consecutive odd integers, starting with N, is expressed as N + (N+2) + (N+4). If that sum is 363, then you have 3N + 6 = 363. Solve for N and you have 119.Since N (119) is odd, the answer and question are valid. (If N had been even, the question would have been invalid, and the answer would have been meaningless. This test is simply a sanity check.) The three numbers are 119, 121, and 123.
Sum means the total amount resulting from the addition of two of more numbers. Therefore, to get the answer, you'll want to add 1015 and 119. 1015 + 119 = 1134.

2023-1015 = 1008
(-117)+(-118)+(-119)=(-354)
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
