Instruction
Good! Let's take a look at the ABS(x) function which returns the absolute value of x. Non-negative numbers will be expressed as they are, but negative ones will be expressed without the negative sign. Have a look:
SELECT ABS(3), ABS(-3);
The above query returns 3 twice. The absolute value of 3 is 3, as is the absolute value of -3.
Exercise
For each character, show its actual stat_modifier value and its stat_modifier's absolute value as the absolute_stat_modifier column.
Stuck? Here's a hint!
Use this expression: ABS(stat_modifier).
