50 = 1 + 2 + 3 × 4 + 5 + 6 + 7 + 8 + 9
50 = 9 + 8 + 7 + 6 + 5 + 4 × 3 + 2 + 1
50 = −0^0 − 1^8 + 2^7 − 3^9 + 4^5 + 5^6 + 6^2 + 7^4 + 8^3 + 9^1
50 = (11 − 1)(1+1)/(1 + 1)
= 2 × (22 + 2) + 2
= 3 + 3 + 33 + 33/3
= 4 + 44 + (4 + 4)/4
= 5 × (5 + 5)
= 6 × 6 + 6 + 6 + (6 + 6)/6
= 7 × 7 + 7/7
= 8 × 8 − 8 − 8 + (8 + 8)/8
= (9 × 99 + 9)/(9 + 9)
50 = 52 + 52 = 72 + 12
