Copilot and chatgpt suuuuck at basic maths. I ws doing coupon discount shit, it failed everyone of them. It presented the right formula sometimes but still fucked up really simple stuff.

I asked copilot to reference an old sheet, take column A find its percentage completion in column B and add ten percent to it in the new sheet. I ended up with everything showing 6000% completion.

Copilot is inegrated to excel, its woeful.
