League of Legends (LoL) Question: CS??

I wrote 108. 114 is the amount of the cs including the spawn of the minions at minutes 10 I guess.

6 minions per wave, 1 wave per 30 seconds (2/min), first 1,5 minute no minions. 8,5 minutes * 2/min * 6 = 102 minions excluding siege minions.

Siege minions work a bit differently. The first siege minion spawns at 2.50 minutes and from there 1 per 1.5 minutes. That means 6 siege minions in the first 10 minutes.

6 + 102 = 108. So it is 108 minions maximum in the first 10 minutes, not 114 :3
