| Description: Equality inference for negatives. (Contributed by NM, 14-Feb-1995.) |
| Ref | Expression |
|---|---|
| negeqi.1 | ⊢ 𝐴 = 𝐵 |
| Ref | Expression |
|---|---|
| negeqi | ⊢ -𝐴 = -𝐵 |
| Step | Hyp | Ref | Expression |
|---|---|---|---|
| 1 | negeqi.1 | . 2 ⊢ 𝐴 = 𝐵 | |
| 2 | negeq 11588 | . 2 ⊢ (𝐴 = 𝐵 → -𝐴 = -𝐵) | |
| 3 | 1, 2 | ax-mp 5 | 1 ⊢ -𝐴 = -𝐵 |
