By way of gaining a minimal experience with how equational proofs look in the present forms of syntax, I will lay out the proofs of a few essential theorems in the primary algebra.
 
By way of gaining a minimal experience with how equational proofs look in the present forms of syntax, I will lay out the proofs of a few essential theorems in the primary algebra.
   −
The first theorem is known as the ''Double Negation Theorem'' (DNT).
+
The first theorem goes under the names of ''Consequence&nbsp;1'' <math>(C_1)\!</math>, the ''double negation theorem'' (DNT), or ''Reflection''.

The proof that follows it is derived from the one that was given by George Spencer Brown in his book ''Laws of Form'', and credited to two of his students, John Dawes and D.A. Utting.  This result is annotated as ''Consequence&nbsp;1'' (''C''<sub>1</sub>) or as ''Reflection'' in LOF.
