NO

Problem:
 +(x,+(y,z)) -> +(+(x,y),z)
 *(x,+(y,z)) -> +(*(x,y),*(x,z))
 +(+(x,*(y,z)),*(y,u)) -> +(x,*(y,+(z,u)))

Proof:
 Unfolding Processor:
  loop length: 3
  terms:
   +(x245,*(x282,+(x283,x284)))
   +(x245,+(*(x282,x283),*(x282,x284)))
   +(+(x245,*(x282,x283)),*(x282,x284))
  context: []
  substitution:
   x245 -> x245
   x282 -> x282
   x283 -> x283
   x284 -> x284
