95 = 12 + 3 + 4 + 5 + 6 + 7 × 8 + 9
95 = 9 + 8 + (7 + 6) × 5 + 4 + 32 × 1
95 = 0^8 + 1^0 + 2^7 − 3^9 + 4^5 + 5^6 + 6^1 + 7^4 + 8^3 + 9^2
95 = 111 − (1 + 1)(1+1+1+1)
= 2 × 2 × (22 + 2) − 2/2
= 3 × 33 − 3 − 3/3
= 444/4 − 4 × 4
= 5 × (5 × 5 − 5) − 5
= 66 + 6 × 6 − 6 − 6/6
= 77 + 7 + 77/7
= 88 + 8 − 8/8
= 99 − (9 × 9 − 9)/(9 + 9)
954=224+524+574+744+764
