I doubt that the boy (or even the man) Jesus could do caculus of speak Chinese. I bet He got tired, hungry, maybe even frustrated (these things seem to be in the Gospel). Yet He is God. This is the MYSTERY and SACRIFICE of the Incarnation.
But none of the things you cite are mistakes, are they? It is not a mistake not to speak Chinese (especially if you aren't Chinese.). It is not a mistake to do calculus, especially if you have never been taught it. It is not a mistake to be tired, hungry, or frustrated. NONE of these things are mistakes.
Humans have limits. They aren't fasting than a speeding bullet, more powerful than a locomotive.
