What's the problem with this method? I figure out tips through mental math, without any paper. This is just explaining how I do that mental math

Yeah you did it in the hardest way possible hahaha

Just subtract 17 from 100 to get the cents. 83. There, done. Or at least 100 - 10 - 7

I can't do mental math that easily. I struggle with visualizing it, I think better in multiples of 5, and subtraction is more intuitive to me
