dividing.
If you calculate 10 + 7 first, you get 17, which still leads nowhere near 18.
Therefore, no matter which common calculation method or mistake you use, the result is never 18.
This makes the statement “Answer is NOT 18!” absolutely correct in every single way!
The text in the picture is 100% accurate because 23 is definitely not equal to 18.
In conclusion, following the proper math rules leads us directly to the true result.
The final correct answer to this puzzle is 23.
