Thread: Hello, newbie needs help.

29- { 5+3 [ 8 x (10 - 8 ) ] -50 }

I do not understand this. This is not offical homework, but I don't want to get behind. Also what do these { } mean

They are just another way of expressing paranthesis.

Something written like this doesn't look very good.

Woah!

So we use other kind of brackets sometimes.

Now to your question.

You have:{ 5+3 [ 8 x (10 - 8 ) ] -50 }

Use PEMDAS or order of operations

1.
2.
3.
4.
5. There's your answer!

What about the 29-
29-{ 5+3 [ 8 x (10 - 8 ) ] -50 }

Ooops! Didn't see that. Then it's 29-3=26

I would just like to point out Jameson, that you can wright brackets with Latex:

I my self prefer to use the singe parantheses, ( )
The other [ ] can be confused with greatest integer function.
And never try to use { } because it deals with sets which are divine.

Of course, considering barbienut doesn't know greatest integers and divine sets (neither do I for that matter) I don't think it's really relevant what you think

although, I personally agree with you. I think it's sort of fun (although I don't think anyone else agrees with my) to figure out which paranthesis pair up. I've also become good at it by using excel.

Hello, barbienut75!

I have questions about what you wrote . . .

. . . . . . . . I assume this is "times"
. . . . . . . . . . . . . .
. . . 29 - { 5 + 3 [ 8 x (10 - 8 ) ] - 50 }
. . . . . . . . . . .
. . . . . . . but is this also "times"?

If so, I can explain the procedure.


Start within the "innermost" grouping symbols.
