Math Wrath is a perk in Fallout: New Vegas.
Effects
You are able to optimize your Pip-Boy's VATS logic, reducing all AP costs by 10 percent. Note that this perk applies across all weapons, but will also stack with weapon-centric VATS perks, like Plasma Spaz or Beautiful Beatdown.
Notes
In addition to saving action points each shot fired during a VATS session, it has the added benefit of making AP regen more effectively (each AP regenerated is worth more). Because of this, repeatedly using VATS mode in combat will allow you to land more shots than normally possible with Action Boy/Girl in a given period of time. Math Wrath also synergizes well with Grim Reaper's Sprint, as you are able to use each 20 AP bonus more efficiently. Whether this is relevant depends entirely on your character build and play strategy.
It has the advantage of being open to the player at level 10, where Action Boy/Girl cannot be taken until level 16, and the two perks complement each other very well for a V.A.T.S.-oriented character.
In Dead Money there is a unique dialogue option with Christine in which the PC says, "Well, at least you still can do math."
