That way it's just 30 48. And removing 3 is easy. 10:01 PM 26 Jun 2019 kai) Follow @venusmartian Replying to @Wparks91 27 2 25 48 2 50 50 25 75 11:50 PM 25 Jun 2019 Shaun Roe Follow @itszerolove Replying to @priusCSGO @nOthing @Wparks91 In my head it ends up working out like "2+4 and add a zero for 60, then 7+8 is 15, so 60+15 is 75.". 4:41 PM 26 Jun 2019
