The fx-250HC uses two standard AA batteries. You may use either rechargeables or disposables, but make sure the two batteries are of the same type and vintage.

I can't get the calculator out of the exponent mode. ex. It gives me 7 -03 rather than .007.

You must change the number display to FIX. Press [MODE][7:] followed by a number betwee 0 and 7. This will set the number of decimal digits. Be warned that the Indicator FIX will be displayed on the screen.
This information is for the FX250D, but I trust it is also valid for the FX-250HC. If it is not, just look in your manual. If you cannot find yours, do not blame me, I cannot get hold of a manual for this calculator.

You can always take the time to play with the [MODE] key followed by [.] or a number. When you press the mode + number, look on the screen to see what indicator appears (deg, Fix, Rad) The one that makes FIX appaear is the one that gets you out of the exponential scientific mode.

Good luck

Substitute for 1/X key

Use the x^-1 key, second row, far left. 1/x is x to the -1 power.

Log I do not know how to...

I have finally worked out how to do log to the base 2 on my FX-83ES after nearly 2 years.
I hope yours is a similar problem.

The calculator must be in MATH mode or it will not work.
press the log button as the useless manual says then 2 then the right arrow on the replay button and then the number you want the log2 off..
Hey presto a correct answer
