A prime number is one that is not divisible by any other number. For example, 2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 etc are prime numbers.
For p = prime calculate p² + 1 First 5 prime numbers: 2, 3, 5, 7, 11 So what's the answer? Prime number - Wikipedia
p² (reads "p to the power 2") = pXp. It's not about doubling. After careful consideration I decided to not hire you as my financial advisor
Wise decision. The main reason I didn't take Marine Biology was because of the math, I did want to work with dolphins and other mammals but knew I didn't want to study that hard.
The fact that the numbers are in a circle implies that you can go round and round, starting anywhere. Obviously that's not the case in the first example. You had to start in the upper right and stop on one round. Why make a circle in the first place? Where is the starting point on this one? I contend the answer would be different depending on where you start.
It's no starting point. This is how it works: you are given enough info to solve the puzzle. For instance, in this case: look at the diagonally opposed numbers. Do you notice a pattern?
