I need the EXACT solution for -7 + square root of 61 divided by 2. I have a Ti-30XA calculator and I don't know how to do this.


It is unclear whether your equation is:

a: ((SQRT61) - 7) / 2
or
b: ((SQRT61) / 2) - 7

For a:
Type 61 SQRT.
Subtract 7.
Equals.
Divide by 2.
Equals. (Should be 0.4051248...)


For b:
Type 61 then SQRT.
Then divide by 2.
Equals.
Then subtract 7.
Equals. (Should be -3.094875...)

Good luck.

Is there an EE button for scientific notation of TI-30XS


On a TI-30XA the EE key is just above the 7 key.

On a TI-30XIIS the EE is the shifted function of the key just above the 7 key.

Ti-84 will power on but no keypad response


Potentially, the batteries are very weak, and you might just need to change them out (4 AAA's). More likely, I think there is something defective with such a calculator. Depending upon how long ago you purchased it, it is possible of getting it replaced. The following is Texas Instruments service rep contact info from there website (as of: June 17th, 2010).

Negative 1/6 *2 3/4


Pressing ( 7 / 8 ) + ( +<>- 2 / 7 ) = will produce the answer on the TI-30XA.

+<>- is the key to the right of the decimal point.

Comma key on TI-84 Plus Siver Edition calculator.


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.
