Comment on A fake Facebook event disguised as a math problem has been one of its top posts for 6 months
SmartmanApps@programming.dev 2 weeks agothe proper way is to group it as 1+(-2)+3
No it isn’t.
you can do it in any order
You can do it in any order anyway
left to right 1-2+3=-1+3=2
addition first 1+3-2=4-2=2
subtraction first -2+1+3=-1+3=2
right to left 3-2+1=1+1=2
What I meant with ““rule”” is the meme questions pray on people not understanding/remembering what the actual rules are
And you showed that you were one of them. Every answer you got other than 4 was wrong, because you didn’t understand the rules. spoiler alert: doing it in different orders never means add brackets to it. Addition first for 10-1+1 is 10+1-1, not 10-(1+1). See previous textbook example
