| Description: Two times a number. (Contributed by NM, 1-Aug-1999.) |
| Ref | Expression |
|---|---|
| 2timesi.1 | ⊢ 𝐴 ∈ ℂ |
| Ref | Expression |
|---|---|
| 2timesi | ⊢ (2 · 𝐴) = (𝐴 + 𝐴) |
| Step | Hyp | Ref | Expression |
|---|---|---|---|
| 1 | 2timesi.1 | . 2 ⊢ 𝐴 ∈ ℂ | |
| 2 | 2times 12403 | . 2 ⊢ (𝐴 ∈ ℂ → (2 · 𝐴) = (𝐴 + 𝐴)) | |
| 3 | 1, 2 | ax-mp 5 | 1 ⊢ (2 · 𝐴) = (𝐴 + 𝐴) |
