In Level 147, your challenge is to reach the target number 70 using only the solo digit 7. The optimal solution requires exactly 3 digits.
Notice how close 70 is to multiples, factorials, or powers of 7. If direct multiplication or division leaves a remainder, look for ways to generate 7 / 7 = 1 or (7 - 7) = 0 to fine-tune your final total.
