200 = 1 + 23 × 4 + 5 + 6 + 7 + 89
200 = 98 + 7 × 6 + 54 + 3 + 2 + 1
200 = 0^6 + 1^8 − 2^4 − 3^9 + 4^7 + 5^5 + 6^2 + 7^3 + 8^0 + 9^1
200 = 2^2 + 14^2 = 10^2 + 10^2
200 divides 49^2 - 1.
200 = (1 + 1) × (11 − 1)(1+1)
200 = 222 − 22
200 = 33 × (3 + 3) + 3 − 3/3
200 = 4 × (44 + 4) + 4 + 4
200 = (5 + 5) × (5 × 5 − 5)
200 = 6 × 6 × 6 − 6 − (66 − 6)/6
200 = (7 + 7) × (7 + 7) + 77/7 − 7
200 = 8 × (8 + 8 + 8) + 8
200 = 99 + 99 + (9 + 9)/9
