83 = 23 + 29 + 31 = 11 + 13 + 17 + 19 + 23, prime number written as a sum of consecutive prime numbers in 2 different ways
Sexy Prime (Primes p such that p + 6 is also prime)
83 = 12 + 3 + 4 + 5 + 6 × 7 + 8 + 9
83 = 9 + 8 + 7 + 6 + 5 × 4 + 32 + 1
83 = 0^8 + 1^9 + 2^6 − 3^7 + 4^5 + 5^4 + 6^2 + 7^1 + 8^3 + 9^0
83 = (11 − 1 − 1)(1+1) + 1 + 1
= (2 + 2/2)(2+2) + 2
= 3 + 3 × 33 − 3/3
= 4 + 4 + (44 + 44)/4
= 5 × 5 + 55 + 5 − (5 + 5)/5
= 66 + 6 + 66/6
= 77 + 7 − 7/7
= 88/8 + 8 + 8 × 8
= 9 × 9 + (9 + 9)/9
