2?3

Could you clarify what you mean by "2?3"? Here are the likely interpretations and quick answers:

• If ? is a binary operator between 2 and 3 (insert +, -, *, /, or ^):

  • 2 + 3 = 5
  • 2 - 3 = -1
  • 2 * 3 = 6
  • 2 / 3 ≈ 0.6667
  • 2^3 = 8 (if exponent is allowed)

• If ? is a single digit to form a three-digit number 2?3:

  • Possible numbers: 203, 213, 223, 233, 243, 253, 263, 273, 283, 293

• If you meant “2 to the power of 3” (2^3), that’s 8.
