Tanjiro loses, Thanos themself can make a shield that can withstand a planet-destroying attack, survived three planet-destroying attacks, survived a black hole, is strong enough to lift 50 quintillion tons, is fast enough to match silver surfer's speed, and is resistant to a gun specifically made to kill him. 1) MCU nerfed a lot of the characters in the comics and this is mostly based on comics, 2) MCU probably would still defeat them
1) Math is not useless, counting and arithmetic operations are really important
2) Math isn't boring, it's just fluent in over 16 million ways to break one's brain
3) And lastly, Not all of math can be applied to real life, I mean; matrixes, most of advanced calculus(Integrals are pretty useful ngl), less than greater than things, etc
