Hello,
If you are the owner of FX-350 as you know this calculator can't do factorize or to find normal distribution. So today I will try my best to share with others all you need is your FX-350 you don't need to spend any penny for new calculator....

1. First change into SD mode ([mode] --> 2)
2. Press 1 then M+ screen will show n=1, press it until n=99 and press couple more time and screen will sow EditOFF  ESC
3. Press 2 (choose ESC)
4. Press ^ screen will show Freq80
5. now press 1313131313... (i don't know why number 13) press it until the input is max.
6. now press (=) twice
7. press AC
8. now you have pre FX-550

example: - now press [shift] --->3 to find normal distribution.

I know this is a hard work (you need to press button a lot of time), but this is an effort for our students that don't have money to buy FX-570. Try it... and give some feedback..

I found this on some blog that I have forgot the address... thans to that guy.. huuuu

step 1 Change the mode to SD
step 2 press 1 and the press M+ till u see the screen EditOFF  ESC
step 3 press 0 2
step 4 press UP at the direction pad and u'll see the screen freq=80
step 5 input 13131313......... (cannot make any mistakes here)
step 6 press = 2 times and u'll see the screen EditOFF  ESC
step 7 press 0 1

now your fx-350 has been hacked to fx-570.

P/S: Some fx-350 calculators can't be hacked and I also dunno why.

hmm, kalau semua step tu tak sangkut, ataupun kalkulator awk tu fx-350MS yg sesuai (kerana ada sesetengahnya tidak boleh) ada sedikit penambahan fungsi dalam kalkulator tersebut, cuba tekan mode, dan akan didapti fungsi EQN MAT VCT yang mana kebanyakkan pelajar suka menggunakan fungsi EQN untuk melakukan pemfaktoran.

lagi satu kalau dalam add math leh guna nak cari normal distribution. step nak guna tu sama macam 570

jadi kalau takat nak guna fungsi EQN MAT dan VCT, tak perlu laa tukar kalkulator fx-350MS. Wink

Sangat menarik perkongsian ini... Akan mencubanya... Sekiranya tidak ada perubahan walaupun sudah mengikut langkah yang betul... agak-agaknya kena kalkulator original mungkin.... Ini anggapan sahaja...
Apa-apa pun terima kasih di atas perkongsian tu tadi ye cikgu. Wink
