Who's teaching you your math skills? I bet it's the same people that calculate the unemployment figures. According to the US Treasury the national debt was approx. $908B in '80 when Reagan took office. Since then it has increased to approx. $15.7T. That's an increase of approx. $14.84T from '80-'12, not even counting the second half of '12. The national debt in 2001 when Bush took office was around $5.8T, jumping to approx. $10.1T in 2008 as he left office. That's a $4.3T increase over 8 years (42.5%!). So at $10.1T in 2009 when Obama took office, the national debt has increased to $15.75T. That's an increase of around $5.65T (35.8%) in 3.5 years.
