-10, -11, -12 -10 + -11 + -12= -33 written simply replacing the '+ -' s that just equal a '-' its simply: -10 - 11 -12= 33
10 ÷ 11 ÷ 12 = (10 ÷ 11) ÷ 12 = 5/66 = 0.07575... ≈ 0.076
The numbers are -12, -11, -10 and -9.
To find the mean you would add up all the numbers 7+9+10+11+11+12 and get 60. Then divide by how many numbers you added by, in this case 6. So 60 ÷ 6 = 10. The mean would be: 10
12/11 = 108/99 10/9 = 110/99 10/9 - 12/11 = 2/99 12/11 - 10/9 = -2/99
that does not make any sense
The error is that the word its should have an apostrophe.

"Find the error, its impossible" which is in the subject of the email should read "Find the error, it's impossible."
10 ÷ 11 ÷ 12 = (10 ÷ 11) ÷ 12 = 5/66 = 0.07575... ≈ 0.076
A "calculation error".
The numbers are -12, -11, -10 and -9.
11/12 × 10/11 = 5/6
The errors are grammatical. The email came to me as follows: "Find the error, its impossible 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20" Error 1: "Find the error" is a sentence and should end with a period. Error 2: "its" is possessive but should be a contraction of "it is:" therefore, it should have an apostrophe. Error 3: "Since "it's impossible" is a sentence, "it's" should have the i capitalized. Error 4: "Since "It's impossible" is a sentence, it should have punctuation at its end. Suggestions are a period or colon. At least two more errors as 1) It's not impossible. 2) Since there are at least 3 and if including the two you included then 5, error is not singular but plural and should be "errors." (The original riddle from Facebook is explained in the related question below.) ***The "11" is BACKWARDS! Found the error. Boom!***
