Question about Texas Instruments TI-84 Plus Silver Edition Graphic Calculator

1 Answer

No matter what problem i type in.. I get an E after the answer and sometimes the answer is not even right.. It does not matter what i type into my calculator.. i get the answer if it is a very simple problem with a little E after it. Say i put in 8+9 and then i press enter.. this is what i get.. 17E0. Why is that. I most of the time get a zero after the e but occasionally i will get some other random number..

You're in engineering notation. This is similar to scientific notation, except that exponents will always be a multiple of 3. For 8+9, you're getting 17x10^0 = 17, which of course is the correct answer.

Press MODE to enter the Mode editor. On the top line highlight NORMAL and press ENTER. On the second line highlight FLOAT and press ENTER. Press 2ND [QUIT] to exit the Mode editor.

My UNIDEN 6.0 is being replaced, if I unplug the unit base will I lose my saved messages?

While I can't say for the phone model in question, I will attempt to enlighten you generally speakig on the matter of message storage. There are 2 types of storage systems and both are commonly used in phone systems, so you will want to do some google research and find out which one you have in your phone unit. ..... volatile memory is temporary so its data will be lost when it losses power ie power cycled and nonvolatile memory sometimes referred to as flash will keep data even after being power cycled. Hope this helps a little, I'm sorry I can't say specifically for your unit.

Hi my iomega 1tb 2.0 usb drive was formatted yesterday to a fat 32 format and now only 429 gb are available. No matter how i try to format, even back to ntfs format i still only have 429 gb...

Sounds like theres a partition hiding somewhere. You dont need any third party software to do what youre doing. Cli start button and in the run box type Disk Management the window which opens you should see all the drives on the computer .... right click on your 1TB and choose delete partition and also any partition which is not allocated now right click again and choose ne partition. Hopefully after all this you have back your 1TB........cheers and please vote

All buttons dial the same line.

Check to see if the one touch button for the cash office is stuck down, sometimes the corner will stick but is hard to notice its down.

I forgot my mobile password. blackberry. i donno what to do. plz help???

There is a flaw in the Curve 8900 blackberries. After you type "BLACKBERRY", it asks you again to type the correct password. but since the password appears unmasked (without the asterisks) - that's the first flaw- there is no way to make mistakes right? well...thats what you might think.

The blackberry Curve 8900 has a serious flaw in the software that no matter how accurate you type your password, after the first try (when you type your password unmasked), there is no way to get back in because it will recognize your password as wrong ( no matter if you typed it right) and you data will be lost... I will notify this to T-mobile today but I will make sure Blackberry also knows about this bug, so they can fix it right away.

Bellum fight drawing the hourglass

It needs to be figure 8 you draw, don't draw it back wards (lot's of us do!) so try starting at a different point. Also it does not have to be huge - just think of writing the number 8 as answer to a math question on the DS. Just keep trying different ways, I sometimes had this problem with the Frog symbols, it's just a matter of triggering the right spots in the touchscreen.
Your game is not faulty.
