Where did I get those numbers on the x-axis?

I put the mean, 95, in the middle.  Then for the numbers on the 
right of 95, I added the standard deviation 12 to the mean 95 
and got 107, added 12 to that and got 119, and added 12 to that 
and got 131.

Then for the numbers on the left of 95, I subtracted the standard 
deviation 12 from the mean 95 and got 83, subtracted 12 from that 
and got 71, and subtracted 12 from that and got 59.
