1492.
980 + 980 + 980 + 980 + 980 + 980 + 980 = 6860
980 + 875 + 436 + 297 = 2588
-45 plus 512 plus 45 plus 56 = 568
-512 + -14 + 312 = -214
512 + -14 + 312 = 810
512 + 13 + 56 + 2124 = 2705
512 + 568 = 1080
512 + 49 = 561
x -512 = 0 Add 512 to both sides of the equation. x = 512
-512-14+312 is an integer, not a fraction.
The answer is: 286123+203 -512 = 285814
The answer = 3510
