278=133+145 ![]()

^^ ![]()
271 / 3 = 91
145 / 5 = 29
133 / 7 = 19
===========
Correction...
276 = 269 + 7
278 = 151 + 127
===========
280 = 131 + 149
282 = 131 151
284 = 127 + 157
286 = 269 + 17
288 = 269 + 19
290 = 127 + 163

292 = 229 + 73
294 = 163 + 131
296 = 139 + 157
298 = 293 + 5
300 = 151 + 149

Uuhh.. will this help..
322 = 111 + 211
324 = 171 + 153
326 = 179 + 147
328 = 131 + 197
330 = 321 + 9
111, 171, 153, 147, 321 and 9 are not prime numbers

what are the rules that make a prime numbers?

Let me try these:
322 = 199 + 23
324 = 113 + 211
326 = 227 + 109
328 = 269 + 59
330 = 227 + 103
Do I get it now? ![]()
"In mathematics, a prime number (or a prime) is a natural number greater than 1 which has exactly two distinct natural number divisors: 1 and itself. An infinitude of prime numbers exists, as demonstrated by Euclid around 300 BC. The first thirty prime numbers are:
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113. "

Thanks Dajana.. you're the greatest..

Oh I forgot about this thread
And I have really, really important math test today ![]()

Good luck! ^_^
PS. do you happen to know of any online lectures on computer math... specifically on IEEE 754 notation?
