41 is a Prime Number, Prime(13)
41 = 12 − 34 − 5 + 67 − 8 + 9
41 = 98 − 76 + 5 − 4 − 3 + 21
41 = 0^6 + 1^9 + 2^1 + 3^7 − 4^8 + 5^2 + 6^3 + 7^0 + 8^4 + 9^5
41 = 4^2 + 5^2
41^2 = 9^2 + 40^2
41 = (1 + 1 + 1) × (11 − 1) + 11
= 2 × (22 − 2) + 2/2
= 3 + 33 + 33/3
= 44 − 4 + 4/4
= 5 × 5 + 5 + 55/5
= 6 × 6 + 6 − 6/6
= 7 × 7 − 7 − 7/7
= 8 × 8 − 8 − 8 − 8 + 8/8
= (9 × 9 × 9 + 9)/(9 + 9)
