Confidence 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!
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)
To 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.
Ah! Ok, exactly what I thought. I just wanted to hear it from someone else, to assure myself I learned from my error. THank you again Bobbym !
Here'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 !
