E3 is displayed after an incorrect answer on TI84

Not always but sometimes simple multiplication or addition displays an incorrect answer and after it is "E3". The capitol E is about half the size of the 3.

Ok there is not a problem. the "E" is the calculators way of scientific notation. So if u were to see 1.70 e3 it would really mean 1.70 x 10^3 which is 1700. If these are small numbers and you are getting these "e" ur calculator is in scientific notation mode. Press "mode" then at the top highlight the word "normal" and hit enter. You will be back in normal calculator mode.

When calculating trigonometric functions you should pay attention to the angle unit used. The TI84 PLUS/SE can use two units: the radian and the degree, As to rounding I do not see why it would ruin your answers which are approximate anyway. Just choose float whithout specifying the number of decimal digits, then when a result is displayed round it yourself to the desired accuracy.

To set the angle unit press MODE, then use down arrow to move highlight to the line RADIAN DEGREE and select the one you want.

Ti-nspire with 84 keypad problems


It seems to me that you get the loading bar when you switch keypads. I just switched keypads, and when I reinserted the TI84 Plus keypad back again I found my last TI84 Plus screen contents still displayed.
As to the RAM cleared message, it probably is related to the batteries being depleted.
To verify battery charge level, you may use TI connect.

Assuming that the input numbers are given by the user:print "Menu"print "1. Addition"print "2. Subtraction"print "3. Multiplication"print "4. Division"print "0. Quit"
a = input("Please make a selection:")if a == 1: x = input("Please enter a number:") y = input("Please enter another number:") answer = x + yprint "%r plus %r = %r" % (x,y,answer)elif a == 2: x = input("Please enter a number:") y = input("Please enter another number:") answer = x - yprint "%r minus %r = %r" % (x,y,answer)
The same goes for everything else just with different signs. Don't forget that "*" is multiplication and "/" is division. Also, for 0. Just use:
elif a == 0: quit

Error Code E3 displayed on Samsung wine cooler model RW13EBSS, even after power off and reset.


"E3" on display for upper zone - error of DC
electric fan for upper zone.

I had an E3 on the upper zone. This fix was simple. Unscrew the 2 screws for the middle tray. Pull tray out as far as you can. Check the wires in the back, those are the wires for the fans in the back. The connectors over time corrode, and break off... All I did was connected the 2 wires that had broken off of their connector directly to each other. E3 went away and the cooler is working as it should now.in

Good day! TELL MY WINE FRIDGE SAMSUNG RW13 Display errors (E3)


Checked out Samsung website, E3 error fixed by simply unplugging the unit for 30 seconds. If come back again... then is possible that it has a thermal sensor, this could probably just the problem.

Additional details could find in this link: HERE

Good luck.

My TI-30XIIS calculator displays an arrow,an DEG, and a K always on my screen whenever i try to do simple multiplication. it says Syntax error and will not compute an answer.............


I had this problem also and just fixed it. I hit 2nd key...don't hold it, (it should say 2nd in the lower left corner across from the DEG) then click the K button (also the divide key). The arrow and DEG will remain, but do not affect simple math calculations. Hope this helps!
