Riddle: Give me an x, I’ll stand to face you. Give me a cross, I’ll turn my back on you. What am I?
The answer of this riddle is the number 9. Here “x” refers to multiplication.
When you multiply nine and nine, the result is 81. In 81, the number 1 looks like it is face to face with the number 8. The word “cross” refers to addition. The numbers nine and nine add up to 18, in which the number 1 looks like it turns it back on the number 8.
Answer: The Number 9 (9 multipled by 9 = 81, 9 plus 9=18).
