Solving @pgliljedahl ‘s problem from today. Can you write 5 one-step equations equal to 1,2,3,4,5 using the numbers 1,2,3,4,5,6,7,8,9,10 each exactly once? You can only use one operation + , - , * , / per equation and have to use each of them at least once. Eg. 2+3=5, 8-4=4, ...
@apharradine@nomad_penguin Tried with 1-4 and was able to end with 0 and 2. With 1-8 I could end even too. I think n/2 must be odd for the last number to be odd.
@apharradine@nomad_penguin I understand why the last number must be odd, but don't know how to calculate the probability of the last number being a certain number. 2/2
@nomad_penguin@apharradine Maybe he would share? My students have taken an interest in this problem, especially after it was retweeted & liked by ppl outside of Canada
