For example, Luke 18:35-43 speaks about a blind man, but Matthew 20:29-34 speaks about two blind men. One may perceive this to be a mathematical contradiction. One explanation is that it is possible that Luke was speaking about one blind man amongst the two that existed there. Another explanation is that Luke and Matthew were speaking about two similar but different incidents that happened in which one incident had two blind men and the other had one blind man.
But if the sceptic wants to find contradictions like this, it might be not very difficult to find many such things in Bible. But so can be with Science-books. For example, if one Science-book says uses π=3.14 whilst another Science-book uses π=3.1416, one can perceive it to be a mathematical contradiction because 3.1416 ≠ 3.1400. But Science-believers may argue that those are written with a convention that since the farther the numbers after decimal points the less the value of the number would be, and so π=3.14 is to be interpreted to be an approximate value of π truncated to some reasonable decimal places rather than to be the exact value of π. I believe that the New Testament is also written that way in their culture. More valuable things are written more accurately and less valuable things are written less accurately, i guess. In the New Testament, more important thing is morality. The number of blind people (whether there had been two blind men or a single blind man) isn't much valuable to the context of the author because the author is putting the focus on a more important thing (i.e., the miracle that Jesus did), just like when the author of a Science-book uses π=3.14 the author is putting the focus on more important things than arguing that the 4th decimal value of π is zero.
If one group of eye-witnesses said that Titanic sank down as it was, whilst another group said that Titanic broke into to before sinking down, it is easy for a sceptic to argue that since the eye-witnesses contradict the sinking of Titanic must be a hoax. But those who have ears may interpret the less valuable part (the breaking of Titanic) to be an approximate explanation relative to a more important/valuable part which is the sinking of Titanic that is agreed by all the eye-witnesses. Even if we assume that the New Testament writers happened to disagree on the number of blind men, they all agree on morality and the resurrection.
