FreeAddSemigroup.toFreeAddMonoid

{α : Type u_1} → FreeAddSemigroup α →ₙ+ FreeAddMonoid α

The natural embedding of the free additive semigroup into the free additive monoid. This is injective (FreeAddSemigroup.toFreeAddMonoid_injective), and its image consists of all non-0 elements of the free additive monoid (FreeAddSemigroup.eq_zero_or_toFreeAddMonoid).
