Oh, dude, mirror primes are like regular primes, but they're all about symmetry and stuff. So, the mirror primes less than 100 are 2, 3, 5, 7, 11, 13, 17, 31, 37, 71, 73, 79, and 97. It's like a fancy math club for numbers that look good from both sides!
Mirror primes are prime numbers that remain prime when their digits are reversed. The mirror primes less than 100 are 2, 3, 5, 7, 11, 13, 17, 31, 37, 71, 73, 79, and 97. So, there you have it - a mirror-prime extravaganza under 100!
Well, hello there, friend! Mirror primes are special numbers that remain prime when their digits are reversed. Let's take a moment to appreciate these unique numbers together. The mirror primes less than 100 are 13, 17, 31, 37, 71, 73, 79, and 97. Keep exploring the beauty of numbers, and remember, there are always more wonders to discover on your mathematical journey.
The odd primes less than 20 are: 3 5 7 11 13 17 19
There are 8 twin primes less than 100. 3,5 : 5,7 : 11,13 : 17,19 : 29,31 : 41,43 : 59,61 : 71,73
In any large range of numbers, more so the higher and larger the range is, there will be more composites than primes. It is far more likely that a given number will be divisible by some number less than the number itself, the higher you go.
5, 7, 13, 17 and 19 can be so written.
Just 7. Any other number divisible by 7 isn't prime.
