Red Herring

Let us look at this math expression:

1+1+1+1+1+1+1+1+1+1*0

One has probably seen tons of "trick questions" like these:

1*2*3*4*5*6*7*8*9*0

Of course, the answer to the second one is 0, but is it the same with the first? If one looks closer, the order of operations will render the answer to be 9. The last multiplication by 0 only acts on the last 1!

This is an example of a red herring.

The Wikipedia page states:
Red herring is an English-language idiom that commonly refers to a type of logical fallacy in which a clue is intentionally or unintentionally misleading or distracting from the actual issue.
