School of Math/Mathmagitician Optimized Way

"Math equals magic" said a mysterious yet powerful Wizard who follows the school of math. unlike magic, math is infinite 

Optimized Usage of Magic through Math part 1

add all your spell slots together and add 5 to it (ex:if you have 4 level 1 spell slots and 2 2 level spell slots you have 4+2(2)=8 spell slots+the optimized usage of magic is the +5(this is your new and optimized mana pool) higher level spell slots equal more spell slots, like a level 8 spell slot equals 8 spell slots). every spell is now going to use your new and improved mana pool. you use 9 spell slots to use a level 9 spell and 4 spell slots to use a 4 level spell. original spell slots are now useless you can't use them at all.

spells now use one less spell slot, (ex: a 4 level spell now uses only 3 spell slots) 

Optimized Cantrips through Math part 1

Every time you cast a cantrip with this feature gain one spell slot, however you have a disadvantage for everything in the cantrip and if you somehow gain a advantage it will do nothing. (because math is something you can only do with hard work, help that gives you the answer is USELESS. So you can use this feature which is basically doing magic with math even though is harder but helps you practice and recover that one spell slot OR you can laze around and not use this feature and use magic without math and use that cantrip through just the magical way and no disadvantage. )

Optimized Cantrips through Math part 2

from the last feature you know don't have a disadvantage since you mastered the math behind Cantrips so it takes less work, however advantages NOW don't do anything to you and EVERY SINGLE spell you do not only cantrips
