I do not agree with the math. If you substitute another symbol (say a ✵) for the numeric "2's", then you have ✵✵ and ✵✵. Count the ✵'s and you have 1,2,3,4. Simple, right? Yet, someone put that lie on the roof of a building; I wonder... why? I can't read minds, so I don't know; but I can guess, because I have seen
liars operate before... here is one example...
WEB: Matthew Chapter 4
 Then Jesus was led up by the Spirit into the wilderness to be tempted by the devil.  When he had fasted forty days and forty nights, he was hungry afterward.  The tempter came and said to him, “If you are the Son of God, command that these stones become bread.”
 But he answered, "“It is written, ‘Man shall not live by bread alone, but by every word that proceeds out of the mouth of God.’”"
 Then the devil took him into the holy city. He set him on the pinnacle of the temple,  and said to him, “If you are the Son of God, throw yourself down, for it is written, ‘He will put his angels in charge of you.’ and,
‘On their hands they will bear you up,
so that you don’t dash your foot against a stone.’”
 Jesus said to him, "“Again, it is written, ‘You shall not test the Lord, your God.’”"
 Again, the devil took him to an exceedingly high mountain, and showed him all the kingdoms of the world, and their glory.  He said to him, “I will give you all of these things, if you will fall down and worship me.”
 Then Jesus said to him, "“Get behind me, Satan! For it is written, ‘You shall worship the Lord your God, and you shall serve him only.’”"
Satan knew Jesus was hungry and with that comes a natural desire for self-preservation. And as every civilized person knows, you need money to survive in this world. Satan also knew who Jesus was and IF he could put a wedge between Jesus and his heavenly father by planting doubt in any of these three areas; then he would succeed just as he had with Adam and Eve. But Jesus knew both his Father and the scriptures and defeated Satan at every turn. He understood the purpose of a lie; to entice disbelief, to twist reality into something it isn't. This applies not only to math on the roof of a barn, but in understanding the Scriptures as well. If you know math, then you won't be fooled and if you know the Scriptures and the one who gave them... you just ignore the "if's". That the stuff faithfulness is made of!!!
