Apply add_nat_SR with 32, 2, λ x0 x1 . x1 = 35 leaving 2 subgoals.

The subproof is completed by applying nat_2.

set y0 to be ordsucc (add_nat 32 2)

set y1 to be 35

Claim L0: ∀ x2 : ι → ο . x2 y1 ⟶ x2 y0

Let x2 of type ι → ο be given.

Assume H0: x2 35.

set y3 to be λ x3 . x2

Apply unknownprop_bb0ea767d8120d2adea9ad10ea34869ec9220dae095b070f3ec062610dcbd414 with λ x4 x5 . y3 (ordsucc x4) (ordsucc x5).

The subproof is completed by applying H0.

Let x2 of type ι → ι → ο be given.

Apply L0 with λ x3 . x2 x3 y1 ⟶ x2 y1 x3.

Assume H1: x2 y1 y1.

The subproof is completed by applying H1.
