32 = 11 + 22 + 33
32 = 12 − 3 + 45 + 67 − 89
32 = 98 − 7 − 65 + 4 + 3 − 2 + 1
32 = 0^1 − 1^8 − 2^7 − 3^9 + 4^5 + 5^6 + 6^0 + 7^4 + 8^2 + 9^3
32 = 4^2 + 4^2
32 = 11 × (1 + 1 + 1) − 1
= 2 × 2(2+2)
= 33 − 3/3
= 4 × (4 + 4)
= ((5 + 5)/5)5
= 6 × 6 − 6 + (6 + 6)/6
= 7 + 7 + 7 + 77/7
= 8 + 8 + 8 + 8
= 9 + (99 + 99 + 9)/9

232 - 1 = 3 * 5 * 17 * 257 * 65537
1032 - 1 = 3 * 3 * 11 * 17 * 73 * 101 * 137 * 353 * 449 * 641 * 1409 * 69857 * 5882353
