The above equation was written on a chalkboard to represent an example of a correctly answered multiplication problem. However, the class prankster went when the teacher wasn't looking and smudged many of the numbers. What did the original problem read?

117*319=37323 not 37283.

Problem occurred at 117*9=1053 not 1013.

After all these years.
