Question

Mr. Guo is thinking of a number. When he takes the absolute value of his number, he gets 15. What could his number be

Answer 1

Absolute value refers to the numerical value only irrespective of the sign(positive/negative) of the number.

 

So if the absolute value is 15, number could be either 15  or  -15.
