The comma key on the TI 84 SE is above the 7 key, and it is just left of (, right of x squared, and below SIN. thats where the "," key is. If you're asking something else, please clearify. My understanding is that you don't know where the comma key is.

I'm not specifically familiar with the TI83 or TI84 but I've used a lot of TI calculators in my time, so I'll give it a try. If your trying to find the antilog of a number in base 10 enter the number and hit the (10 to the X) button. If you're trying to find the antilog of a number in in base e (natural log), enter the number and hit the (e to the X) button.

Press the 2nd key (yellow one) and then press the UP arrow to increase brightness or down to decrease but seems like you to need to press UP arrow.

### I have a TI-84 and when i put a negative number it appears Ans before how can change that?

Use the (-) key to the right of the decimal point key when entering a negative number. The - key to the right of the 6 key is for subtracting something from something else. In order to subtract from something, if you don't specify anything then the calculator uses the previous answer as designated by "Ans." The same thing happens with the + key for example, because it adds something to something else.

That is what I get with your numbers on the TI84 Plus Silver Edition 0.1870313608. I get the same on the TI83 Plus. What can I say?. Apart from an error entering the numbers ( a 6 for a 9, a 3 for an 8) I cannot think of anything else. Sorry.

### I can't put a negative number in the matrix without a syntax error

Use the (-) key just to the right of the decimal point, not the - key. The second key is for subtraction.

### Is there a positive/negative sign all in one on the ti-84? like to use for the quadratic formula... -b (plus or minus[symbol here?]) the square root of... the rest

No. The calculator can calculate either value at one time, but not both. You can calculate the positive and then the negative (or the other way around), but a single calculation cannot produce two answers. A calculation can produce, for example, a list with two elements, but that's still a single result (a list).

### I when i power -3 to the second i get -9 when it should be just 9

No, is giving you the correct result. When you negate 3-squared, you should get -9. If you want to square negative three, you need to type it in as ( (-) 3 ) ^ 2 or ( (-) 3 ) x^2

There is a difference between (-3)^2 and -(3^2). If you omit the parentheses, the calculator will interpret it as the latter.

If in doubt, use parentheses.

### I ask my TI-83 Plus to calculate (-64)^(3/2) The TI-83 Plus says the answer is -512i, but I think the answer should be 512i. Is the calculator wrong or am I?

You're both right, in a way. (-64)^3 is -262144. The square root of that is +/- 512i. Take your choice as to the sign.

For what it's worth, the TI-84, TI-86, TI-89, and the HP 50g all go with the negative value.
