> 1 + 10% is 0.11. I know adding % has multiple conventions, but this one seems odd, I'd interpret 1 + 10% as "one plus 10 percent of one" which is 1.1, or as 1 + 10 / 100 which happens to be also 1.1 here The only interpretation that'd make it 0.11 is if it represents 1% + 10%, but then the question of 10% + 10% is answered: 0.2 or 20%. Or maybe there's a typo and it was supposed to say "0.1 + 10%"
