How do i type a problem with parentheses? - Texas Instruments TI-30XA Calculator

The same way you type in any negative number. Press the (-) key then enter the digits.

pemdas, parentheses,exponent,multiply,divide,add,subtract. best I can do been out of school for awhile! Hope it helps.

Just use the same parentheses keys. The 30Xa will let you nest up to fifteen sets of parentheses.

Contrary to what you may be thinking, parentheses are necessary to ensure that calculations are performed as intended. If you were using stacked fractions that may lift some ambiguities, but since you are not using parentheses anything goes.
Here is one interpretation of the expression. I am quite sure you will not be able to find it without inserting the necessary parentheses.

You are trying to use a command or a function that requires you to give it some information to use. The information required is supplied between parentheses. What is inside the parentheses is called the argument(s). Each argument must have a certain type of data : scalar, vector, list, matrix. It happens that one of the arguments in your command or function must be of type list. Before calling the function you must have defined (created) that particular list and populated it with necessary values.
That is all I can say, because I have no idea what you are trying to do.

The FOIL Method is a process used in algebra to multiply two binomials. The lesson on the Distributive Property, explained how to multiply a monomial or a single term such as 7 by a binomial such as (4 + 9x).
But, what if there was a binomial instead of a single term outside of the parentheses? That is, what if a binomial was being multiplied by another binomial? An example of this is given below.

FOIL stands for:
First - Multiply the first term in each set of parentheses Outer - Multiply the outer term in each set of parentheses Inner - Multiply the inner term in each set of parentheses Last - Multiply the last term in each set of parentheses Now let's give it a try in our problem. We'll start by multiplying the first term in each set of parentheses and then marking down the answer below the problem.
Now we will multiply the outer terms and again mark down the answer below the problem.
And the Inners.
And finally the last terms.

To do fractions on the TI-83, you must use parentheses.
The parentheses buttons (there are two of them, facing either way) are near the upper right corner of the buttons on the calculator.
To write a fraction, you must enclose it in parentheses, using the divide button (the slash) as the fraction sign (the line between the numerator and the denominator)
For example, this would be one half:
(1/2)
And this would be one third:
(1/3)
As long as the numbers are confined between parentheses, with no other numbers in there besides the fraction, they will act as a single group.
Don't ever be afraid to use plenty of parentheses, either!
For example, if you wanted to add one half to one third, and then multiply it all by three, the following would definitely be acceptable:
((1/2)+(1/3))*3

Hi,
If the default angle unit is not degree, you must set it to degree by pressing the [DRG] key. Once this is done you type
170 [SIN] [ * ]20 [ENTER]

If it feels awkward to enter the command this way you must insert parentheses to make sure calculator is evaluating the sine of 170 , not the sine of 20*170
20 [*] [( ] 170 [SIN] [)] [ENTER]
Notice that the parentheses enclose 170 [SIN]. The sine of 170 will be computed first, then the result is multiplied by 20.

Hope it helps.
Thank you for rating this solution.

Another (easier) option is to type 1.86 EE 3.
