Do you mean something specific by "e"? A few common meanings — tell me which you want:

- The mathematical constant e ≈ 2.718281828… (base of natural logarithms). Quick facts: e = lim_{n→∞}(1+1/n)^n = sum_{k=0}^∞ 1/k!; d/dx e^x = e^x; Euler’s identity: e^{iπ} + 1 = 0.
- The letter "e" (English alphabet).
- Scientific notation marker (e.g., 1.23e4 = 1.23 × 10^4).
- Electron (symbol e−) or elementary charge.
- Email (e-mail).

Or was that a typo? Tell me which one and I’ll expand.
