um you are correct that decem means 10 but actually decim also means ten for numbers 12-17 its like a place holder

doudecim is dou + decim which is the same as 2 + 10 or 12

quindecim is quinque + decim or 15

this pattern continues in the 20 numbers but with viginti

ex) vinginti dou is 20 + 1 or 22

i though i would explain this beacuse this place holder pattern applies in many langauges with latin like the romance launguage branch
