If the numbers can be repeated and the numbers are 0-9 then there are 1000 different combinations.
There are 167960 combinations.
There are 5245786 possible combinations and I am not stupid enough to try and list what they are!
The four possible combinations are:A = (+, +)B = (+, -)C = (-, +) andD = (-, -)In A and D, the two numbers have the same signs and the multiplication gives a positive answer.In B and C, the two numbers have different signs and the multiplication gives a negative answer.
The rearrangement of 5 figure numbers will be 5x4x3x2x1 which is 120 combinations, when you don't repeat a number.
If you can repeat the numbers within the combination there are 10,000 different combinations. If you cannot repeat the numbers within the combination, there are 5040 different combinations.
There are: 17C5 = 6188
Assuming 9 numbers chosen from 56, with no repetition allowed, there are 7575968400 possible combinations.
Assuming that repeated numbers are allowed, the number of possible combinations is given by 40 * 40 * 40 = 64000.If repeated numbers are not allowed, the number of possible combinations is given by 40 * 39 * 38 = 59280.
There are 7 combinations. Each combination excludes a different one of the seven numbers.
