33 = 3 × 11

33 = 1! + 2! + 3! + 4!

33 = 15 +25

33 = 1 + 1 + 2 + 3 + 5 + 8 + 13

33 = 12 + 34 + 56 − 78 + 9

33 = 98 + 7 + 6 − 54 − 3 − 21

33 = 0^6 − 1^8 − 2^9 − 3^7 + 4^5 + 5^1 + 6^4 + 7^3 + 8^2 + 9^0

33 = 11 × (1 + 1 + 1)
= 22 + 22/2
= 33
= 4 × (4 + 4) + 4/4
= ((5 + 5)/5)5 + 5/5
= 6 × 66/(6 + 6)
= (77 + 77 + 77)/7
= 8 + 8 + 8 + 8 + 8/8
= 99 × (9 + 9 + 9)/(9 × 9)
