There is a missing operator:If it is a plus: 77 + 2 = 79If it is a minus: 77 - 2 = 75If it is a times: 77 x 2 = 154If it is a divide: 77 / 2 = 381/2 = 38.5

7*x - 5 + 14 = 77*x + 9 = 77*x = -2x = -2/7x equals minus two sevenths

2 times 7 equals 154.
2 - 7d = -75 7d = 2 - (-75) 7d = 77 d = 77/7 d = 11

77 x 98 = 77 x (100 - 2) = 7700 - 154 = 7546
2 + 77 + 899 + 7464867 + 784764 - 56788 + 5677 = 8,188,144
The missing number is 49. This is why: 1 plus 2 equals 3, then 3 squared is 9. 2 plus 3 equals 5, then 5 squared is 25. Therefore, the missing number must be 49 to make the number sentence (3 plus 4 equals 7, then 7 squared is 49) true.
