Wait!? Magic uses math?!

In a faraway land; I mean in another world, our protagonist Sigma was transported to another world like any other Isekai novel out there

After his death, he was granted no cheat abilities as the other world has no need for these abilities or rather the goddess is just too lazy to grant one.

Anyways, this new world uses magic but with a catch. Instead of a chant, one requires to solve mathematic questions in order to summon said magic.

And thus, our stupid otaku Protagonist struggles to learn each topic and formulas in order to rise as the best mage in this new land
