45
its just 9x5 which is 45
45 + 9 = 54
9 plus 2 plus 2 plus 45-678 is equal to -620.
18 + 36 + 45 + 9 + 9 + 54 + 27 + 72 + 81 = 351
45 with the difference of 9 = 54
45
36 + 9 = 45.
1/5 = 9/45 2/9 = 10/45 19/45
-6x+9 = 45 -6x = 45-9 -6x = 36 x = -6
18+(9*3) = 45
-45 over 9 = -5 -5 plus 5 = 0 QED -45 over (9 plus 5) is a different matter and = -3.2143.
