minus-squarerockSlayer@lemmy.blahaj.zonelinkfedilinkEnglisharrow-up2·edit-22 days agoWhat’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
minus-squareLung@lemmy.worldlinkfedilinkarrow-up1·edit-22 days agoYeah 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
minus-squarerockSlayer@lemmy.blahaj.zonelinkfedilinkEnglisharrow-up3·2 days agoI 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
minus-squarefarmgineer@nord.publinkfedilinkEnglisharrow-up3·edit-22 days agoMine: ends in not 00, so add whatever makes the ones digit a 9 (7 in this case). make the cents even -> .20 (add .03) go to 100 (add .80) I think, anyway. I can mostly just look at it and know.

minus-squarerockSlayer@lemmy.blahaj.zonelinkfedilinkEnglisharrow-up2·2 days agoThis is how I do mental math. Figuring out (100-15)-2 is a lot easier than 100-17
