I would like to calculate for example 5x10 + 3x12-6X 45+ 7x8= total, what should i do step by step to get that result at once without first doing the multiplication and then addiing up the results? Thanks in advance, Margarita
With a number displayed, pressing the M+ key adds the displayed number to the contents of the running memory, and stores the result. Pressing the M- key subtracts the displayed number from the memory and stores the result in the running memory.

Unless I am failing to understand your problem, just combine like terms to get:
9x^2+2x+4 and then enter those coefficients into the quadratic solver.
That will get you the two answers -- both of them will be complex.
If you wanted to turn those two answers into factors (complex) of the original equation simply
change the signs on each and put an x in front.
Of course, the quadratic formula would also work.

I had the same problem too. I just bought it and I was trying to turn it on but it wouldn't though the manual said that it was supposed to automatically when the tab was pulled out. Good news: the Reset button on the back works. I pushed it for some time with the end of a toothpick and it worked.
hope it helps.

Hello,
[OPTN][LIST] scroll right till you find %. Press the function first then the number. It gives you the percent.
Hope it helps.

Hello,
I am only looking for a plausible cause of the error, because I do not believe your calculator can make such a mistake. I think you accidentally activated the Exponential display format and did not pay attention to the small, raised -03 that came at the end of the number displayed. It is a common mistake for those not very familiar with Scientific or exponential notation.
Let us try to reset your calculator to the normal (floating point) format.
Press the [MODE] key a number of times until you reach a screen that has FIX, SCI, NORM and under each one a number (FIX 1, SCI 2), Norm 3). To have the number of decimal place you gave in your result (4 decimal digits), you press 1 to select Fix then 4.
Be aware that scientific calculators usually stop displaying results in floating point format ( 0.0000045 ) if the number is smaller then 0.001. So basically, 0.00099 will be displayed as 9.90-04, -04 being raised above the level, and in smaller size.
Hope it helps.
