Hi AIM TO CRACK GMAT!

Just to verify, are you multiplying the 2-digit number "&^" times the 3-digit number "*^&"? I only ask because we typically write the longer number on top! Just want to make sure that no symbols are missing!

Hey Whit.... The question simply asks you to multiply the reverse of ^&...that is ^& multiplied by &^ and the answer you get is &@&.... THanks alot buddy... and plz use sum numbers so that its easier to be understood for a starter like me...

The answer is D

The clue is the & sign being repeated on both the ends of the 3 digit number.

[spoiler]21*12 = 252[/spoiler]

Because the symbols are not different. If you reverse 11, then the symbols are the same for both
numbers.

It would look like ^^ * ^^ = ^&^
