I'm new to D&D and I'm playing with 5e. With creating a character I chose a half elf. So it says I get +2 Charisma and +1 to 2 other stats of my choosing. My base stat array was as follows:
Str: 8. Dex: 8. Con: 15. Int: 12. Wis: 15. Cha: 15
I understand you calculate the modifiers by subtracting 10 then dividing the difference by 2 and rounding the quotient down. So my question boils down to do my race modifiers completely negate the calculations thus overtaking them or are they simply added to the calculations.
