Quick questionHere's an easy thing : I did the error of doing this : Which is clearly false. I know what is the correct way of doing it, because the real answer is positive one. But just to know, I should have done BEMDAS to have avoided that incorrect way of doing ? Right ? (It concerned the priority of operations?Just want to be sure I've learned correctly from my error) Thank you ! Last edited by AlAllo (20130705 07:29:36) #2 20130705 07:39:56
Re: Quick questionHi; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #4 20130705 07:44:40
Re: Quick questionTo check your work you can use a calculator or google's calculator. They never make a mistake with the order of operations. If you do not get their answer you know you did not follow the order of operations correctly. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #5 20130705 07:45:43
Re: Quick question
That's what I did, but I wanted a human approbation also ^^ Thank you again ! SOmetimes, I need to have more confidence in what I do. ( I hate when I lack it) #6 20130705 07:54:36
Re: Quick questionConfidence comes from doing something and getting good results. When you get bad results or mixed results your confidence will waver. Doubt will set in.
Here, I would trust any calculator over 10 bobbym's any day of the week and twice on Sunday. Look at what it did: Now anyone could do it by just following the rule that parentheses and nested ones go first! Wunderbar! In mathematics, you don't understand things. You just get used to them.
