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

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! :) - Aug 21st 2006, 04:17 PMbarbienut75
What about the 29-

29-{ 5+3 [ 8 x (10 - 8 ) ] -50 } - Aug 21st 2006, 04:52 PMJameson
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. - Aug 21st 2006, 06:52 PMQuickQuote:

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.

We have: .
