Number Detective . 17 | Kid'scape
Hey kids! I'm the Number Detective and my numero uno job is to track down numbers all over the city and find out what they're up to.
My first find wasn't an easy number and even sort of hard to see ... 17. It was above the side entrance of a church off Hanover Street in Boston's North End.
Here are three possible ways of seeing seventeen ...
17 = 3+3+3+3+3+2 ... + + + + + .
17 = 4+4+4+4+1 ... + + + + .
17 = 5+5+5+2 ... + + + .
Seventeen is the seventh prime number. A prime is a number which can only be divided by one and itself. The first seven prime numbers are 2, 3, 5 7, 11, 13 and 17 (1 is not prime since it only has one divisor, itself). It's also the result of adding the first four primes together, 2 + 3 + 5 + 7 = 17. For some mysterious reason, 17 is also considered to be the least random number, that is the most likely to be picked as a number chosen at random. We chose it by chance as our first number.
