It's funny how some people here can't even grasp the concept of percentages as multipliers, and instead is turning them straight into decimals. You guys need to pay more attention in math class. :3
At Jomkiro: You reset to increase your $/sec exponentially. You have probably never played Cookie Clicker, and have no idea how insanely fast you recoup your losses upon resetting. And the reason your comment was downvoted in the first place was probably because it held little in the way of actual feedback that can help the developers improve the game.
M3GAM0S3S is right. The number shown on the fields when your mouse is over the amulet on the lower left indicates your XP gain as compared to the base gain on the field indicated, therefore a number of 2 on a field indicates you have gained approximately twice the XP gain on said field. Not that what I said is actually helpful. :P
sounds like someones been cheating :P
