To make the numbers 1 to 9 equal 99 by adding them, you would arrange them as follows: 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 = 45. Then, you would add the remaining numbers in reverse order: 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 = 44. Finally, you would combine the two sums: 45 + 44 = 89.
(9x8)+(7x6)-(5x4)+((3+2)x1)
The average of the numbers 148, 99, and 119 is 122.
It equal 792.
1, 3, 5, 7, 9, 11 and just keep adding two until you get to 99.
49.5
You can't if its just adding and subtracting. If you can multiply and divide then: 9 * 8 = 72 5 * 6 = 30 30 + 72 = 102 102 - 3 = 99 Notice I haven't used all of the numbers... I don't know whether you were supposed to...
9x11
99 + 99 = 198
99
There are infinite numbers, but 11* 9 is fine.
-99 and 146
99 + (99 / 99) = 100
45 and 54
(33,3)(11,9)
1, 3, 5, 7, 9, 11 and just keep adding 2 until you get to 99.
33 x 3 = 99
97 and 2
