If the numbers can be repeated and the numbers are 0-9 then there are 1000 different combinations.
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.
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.
Assuming 9 numbers chosen from 56, with no repetition allowed, there are 7575968400 possible combinations.
56 combinations. :)

If the numbers can be repeated and the numbers are 0-9 then there are 1000 different combinations.
The associative law of addition refers to the fact that numbers can be grouped in different combinations and the answer will still be the same.
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.
There are 167960 combinations.
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.
Just 1.

If the numbers are allowed to repeat, then there are six to the fourth power possible combinations, or 1296. If they are not allowed to repeat then there are only 360 combinations.
there are 13,983,816 combinations.
