Convert a Casio fx-350MS Calculator into fx-570MS

The scientific calculators used by many students in secondary schools and colleges are Casio fx-350MS and fx-570MS. Casio fx-570MS has more functions than fx-350MS. However, it is possible to convert a Casio fx-350MS calculator into fx-570MS.

After the conversation, however, not all fx-570MS functions will be available. The keys layout will change, some following fx-350MS, some following fx-570MS and some different from both 350MS and 570MS. You have to test it out by yourself.

These are the functions added to the fx-350MS calculator after conversation:

COMP, SD and REG mode: Added CONST and CONV function only. Other fx-570MS functions are still unavailable.

CMPLX and EQN mode: All functions will be available.

BASE-N mode: All functions will be available except some LOGIC functions.

MAT and VCT mode: No function available. Matrix and vector cannot be used.

To convert a Casio fx-350MS calculator into fx-570MS, follow these steps:

1. Press [MODE] and select 2 (SD).

2. Press 1.

3. Press [M+] eighty-two times. It should display "EditOFF ESC".

4. Select 2 (ESC).

5. Press ^ (REPLAY UP).

6. Press 131313131...... until no more numbers can be entered.

7. Press [=] two times. It should display "EditOFF ESC".

9. It should display "1          _". Press [AC].

10. Press [MODE] and you will notice that your calculator has the fx-570MS functions. Well done.

To cancel this and return to fx-350MS, just press [ON]. Start over from step 1 to convert again. So if you want to remain in fx-570MS, you can only press [AC].

NOTE:

1. The method above may not work for some older or non-original versions of fx-350MS calculators. For those calculators, you may not be able to press [MODE] at step 10, or the screen may show some strange displays. In that case, it is not possible to convert the calculator into fx-570MS.

2. The method above does not work for fx-350ES (Natural Display) calculators.

3. As I stated above, after converting your fx-350MS calculator into fx-570MS, only some but not all fx-570MS functions will be available. Also, the keys layout will change.

The girl that I hate

When I was in primary and secondary school, I had many friends, but I also had an enemy. I won't mention her name here, I am just writing about the reasons I hated her.

I knew her since Standard 2. Initially, there were 49 students in my class. However, my class had 8 columns and 6 rows of seats, which was enough for 48 students only. Therefore, an extra table was added behind the class. This girl sat on that seat at first. Then in May 2003, someone in my class transferred to another school. The teacher rearranged the students' seats in class and as a result this girl sat beside me. This was how I began to know her.

In the beginning, I was willing to be friends with her. However, the problem was that she liked to disturb me and then tell the teachers that I disturbed her instead. The teachers were very unfair. They always believed her whenever she made a report about me, but they would not believe me whenever I made a report about her. The Chinese teacher would punish me without allowing me to explain, the Malay teacher would force me to admit that what the girl reported was true by promising she would not tell the principal about that, while the English teacher kept saying that the girl would not have made a report if I didn't do anything.

In Standard 3, a temporary teacher came to our school and she taught Chinese in our class for three months. During that time, this teacher often let us have group activities. I was in the same group with the girl and she was a terrible group member. She wasn't the leader but she always wanted to make all decisions for our group by herself. She often complained to the teacher that I was uncooperative. This teacher was unfair too. She kept telling me not to make reports about small issues, but yet she allowed the girl to do so. In the end, our group was ranked the second last among all groups.

However, in Standard 4 and 5, I and the girl became good friends. This was because we had common friends at that time and we were also living quite close to each other after I moved to a new house. She stopped disturbing me or making reports to the teacher about me.

In Standard 6, the girl's mother asked my grandparents to send her home after school every day since we were living in the same area, and my grandparents agreed. In the beginning, I was happy about that, hoping that it would further improve our friendship. However, this turned out to be really terrible. Since she knew everything that I did in class, she often threatened to report my wrongdoings to my grandparents if I didn't follow her instructions. She was essentially blackmailing me. For a few times, I was scolded by my grandparents because of her reports. My grandparents believed very much in what she said. Because of that, I began to hate her again.

In Form 1, the girl studied at the same secondary school with me. I immediately rejected her mother's request to let my grandparents send her home again. During the first few weeks, a few Chinese students in school kept disturbing me for no reason. Later, I took revenge by damaging someone's bottle. Since those students were her friends, the girl reported that to my grandfather. As a result, my grandparents scolded me badly.

Since then, I hated the girl very much. I would never forget what she had done and I would never be friends with her again. Some other students in my school disliked her as well because of her attitude.
