There is not the slightest difference between them. Regardless of how they appear on the calculator or the screen they are parentheses.

I am trying to add/subtract & multi/divide with a TI 30XS. I can't close the parenthesis. I'll enter the number, then x10n, the exponent, but when I try to close the parenthesis it display

Are you opening the parentheses in the first place? If you don't have a left parenthesis then you don't need a right parenthesis.

Could you post the exact sequence of keystrokes you're using?

7-2[3-2(x-4)] I receive a sytax error at the ending bracket

The square brackets [] are used for arrays and lists. Keep using parenthesis () instead.

7 - 2 ( 3 - 2 ( x - 4 ) )

What are you trying to do? If you are just trying to solve a problem that is in your math book, then parentheses will act just as brackets, for example: [2(1+1)] = 4 (2(1+1)) = 4 These statements are exactly the same to your calculator. Just make sure to complete all of the parenthesis. If you are trying to do something else, from reading the calculator manual I was not able to find support for brackets.

How do i put brackets in a problem

Use the parenthesis above the 8 and 9 keys. Don't use the curly braces on those shifted keys (those are for lists) nor the square brackets on the multiply and subract keys (those are for arrays).

I cannot find the way to make negative powers of ten on this calculator, and also how do I insert brackets into an equation? Thanks if you can help here.

For negative numbers (not just exponents), use the +()- key to the right of the decimal point. For brackets, use the parenthesis keys above the 8 and 9 keys. You can nest more than one set if needed.

I have a TI-30XS Calculator and cannot figure out why the thing won't work when I try to divide numbers with scientific notation. The calculator appears to be adding exponents when it should be...

One solution that you might try is to put the scientific numbers in parentheses. For instance open parenthesis, type in the first scientific notation then close parenthesis, next hit the divide key and then open parenthesis and type in the 2nd number in scientific that you are dividing by and then close parenthesis. Hit enter or =. I'm not sure if this will fix your problem, but it is worth a try.

Abs( and square roots

The missing error means that you did not close the parenthesis. When you use a square root or absolute value it always gives you the left parenthesis, (, but you need to close it with a right parenthesis, )
