4 * 4 - 4 / 4 = 15
Well, honey, to make 15 using only the number 4, you can do 4 + 4 + 4 + 4 + 4 - 4 = 15. It's not rocket science, just basic math. So go ahead and impress your friends with your newfound arithmetic skills.
To get the number 57 using only the digits in 7312, you can subtract 31 from 73. Specifically, 73 - 31 = 42, and then add 15 (which is 3 + 12) to get 57. Therefore, the calculation can be expressed as (73 - 31) + (3 + 12) = 57.
The only way I can see to reach the answer of 17 is: 8 + 15 + 4 + 4 = 8 + 1 + 4 + 4 = 17. I hope that using the "5" as a power is acceptable.
if your using whole numbers, u can only use 3
A number is prime if it has only 1 and itself as factors. For example, 7 is a prime number because it has only 1 and 7 as factors. 15 isn't a prime number because it has 1, 3, 5, and 15 as factors.
you can not do anything to get 60
(4 times 3) plus 2 plus 1
The answer is 15.

x 15 is faster then the sr71 blackbird who can only reach a speed of mach 3.2 which is 3 times the speed of sound but the x 15 can reach mach 6.72
The cardinality of 15 is equal to the number of elements in the set. Since 15 is only one number, its cardinality is 1.
Only 9 and 15 are odd so the rest can be rejected. 9 is not a triangular number so only 15 is odd and a triangular number.
