∀[a,b:ℕ]. ∀[A,B:ℝ(a × b)]. (A + B ∈ ℝ(a × b))
Proof
Definitions occuring in Statement :
real-matrix-add: A + B,
rmatrix: ℝ(a × b),

uall: ∀[x:A]. B[x],
member: t ∈ T
Definitions unfolded in proof :
rmatrix: ℝ(a × b),
uall: ∀[x:A]. B[x],
member: t ∈ T,
real-matrix-add: A + B,
int_seg: {i..j-},
lelt: i ≤ j < k,
and: P ∧ Q,
le: A ≤ B,
nat: ℕ
