Short Answer: No, you cannot add percents like that.
Complete Answer: If you increase 1% 10 times, you are doing x*1.01 ten times, which expanded would be x*1.01*1.01*1.01 etc.... which can be re-writen as x*(1.01)^10. By evaluating this, you get x*1.10462212541120451001. This is quite different from increasing 10%, which would be done by doing x*1.1
