Question about Casio FX-9750GII Graphing Calculator

I just want to be able to put a number in, say 120 and get all of the factors of that number, i.e. (60,2)(40,3)(30,4)(24,5)(20,6)(15,8)(12,10)from my calculator.

There is a program on page 253 of the manual (http://support.casio.com/manualfile.php?rgn=5&cid=004002013) to get the prime factors of any number. You could modify the program to get all the factors.

Another way would be to do it manually. I start with the number 1 and go up to the square root of the number. The square root of 120 is 10.95, so let's go up to 11. Using 120 as an example:

120 /1 = 120 thus factor is (1, 120)

120/2 = 60 thus factor is (2, 60)

120/3 = 40 thus factor is (3, 40)

120/4 = 30 thus factor is (4, 30)

120/5 = 24 thus factor is (5, 24)

120/6 = 20 thus factor is (6, 20)

120/7 = 1.7 thus 7 not a factor

120/8 = 15 thus factor is (8,15)

120/9 = 13.3 thus 9 is not a factor

120/10 = 12 thus factor is (10,12)

120/11 = 10.9 thus 11 is not a factor.

Good luck.

No, your calculator cannot factor polynomials. You need a calculator that has a CAS (computer Algebra System)

Yes Casio sells calculators with CAS: The FX-Algebra 2.0 and 1.0, the FX-9860GPLUS/GII SD, the GRAPH85 or 80 and the Graph 100+. You also have the CLASSPAD Series 300PLUS and 330.

TI and HP also have CAS calculators.

I believe factors can be calculated on any basic calculator.

Starting with 1, increasing by 1 until you get to square root (number) + 1

Let's do an example.

28

square root (28)+1 = 6

Factors

1, 28/1=28

2, 28/2=14 14*2 - 28 = 0 (when you divide, you get no decimal)

3, 28/3=9.33333 - not a factor - doesn't go in evenly

4, 28/4 =7

5, 28/5=5.6 - not a factor - doesn't go in evenly

6, 28/6=4.66666 - not a factor

So now we can list our factors - 1, 28, 2, 14, 4, 7

Putting them in order, we get 1, 2, 4, 7, 14 and 28.

Good luck,

Paul

Turns out to be the = key. I just double-checked it and it's true.

Do a calculation like 10 divided by 2. Every time you enter a number and then hit the equal key, it will be divided by 2.

The polynomial cannot be factored in the set of Real numbers: The roots of the polynomial equation are complex.

You should use the command**cFactor(** found under F2:Algebra> A:Complex>2:cFactor(

However, you should set the Mode Complex>Rectangular, and the EXACT/APPROXIMATE mode to Exact, otherwise your roots will be in decimal representation.

This calculator does not have a key that you can use to find the prime factor of an integer.

You can however use the calculator to find the factors

1.** If number is even divide it by 2**

Keep dividing by 2, while keeping track of how many times you divided by 2.

If you divided 5 times by 2 before getting an odd number, then your first factor is 2^5

2.**Now try dividing by 3**, keep track of the number of times you divided by 3 before you could not divide by 3 any more. If you divided 0 times by 3, your second factor is 3^0, or 1 and 3 is not a factor.

If you divided 4 times by 3, your second factor is 3^4

3.**Divide by 5,** until you can't any more. Keep track of the number of times you divided by 5.

4. Divide by all other prime numbers 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, etc. For each prime number, keep track of how many times you divided by it, until you could not any more.

**Example: 23100**

*Division by 2*

23100/2=11550 ---------> 1 division by 2

11550/2=5775 ----------> 2 divisions by 2

Note that 5775 is not divisible by 2.** No more divisions by 2. **

First factor is 2^2

*Division by 3:*

5775/3=1925 ----------> 1 division by 3

1925/3=641. 66667 Not an integer. No more divisions by 3.

**2nd factor is 3^1**

*Division by 5 (number ends in 5)*

1925/5 =385 -------> 1 division by 5

385/5=77 ----------> 2 divisions by 5 and no more (quotient does not end in 0 or 5)

**3rd factor is 5^2**

*Division by 7 *

77/7=11 --------> 1 division by 7, and no more

**4th factor is 7^1=7**

*Division by 11*

11/11=1

**5th factor is 11^1=11**

Try pressing an operation key twice.

For example to multiply any entry by 15, you would enter 15, press the multiplication key twice. Now to calculate the products of you list of entries by 15, you just enter number in your then press =. c.then the second number and =, etc.

How to do constant multiplication or division on the Canon P170-DH calculator

This process actually requires fewer keystrokes than other calculators. Basically, just do the first problem

and then do the next items with just the next number and the EQUAL key. For example,

*** Constant Multiplication ***

2 (multiply key)

10 (= key)

(The answer 20 shows on the screen. Note, the 2 is still stored as a constant without doing anything, just continue)

4 = (shows the answer 8 on the screen)

20 = (shows the answer 40 on the screen)

100 = (shows the answer 200 on the screen)

*** Constant Division ***

10 (divided by key)

2 =

(shows the answer 5 on the screen, the 2 is still stored as a constant without doing anything, just continue)

100 = (shows the answer 50 on the screen)

500 = (shows the answer 250 on the screen)

4 = (shows the answer 2 on the screen)

oh yeah, you must've archived x, that is, you put a number onto the x variable so that the calculator calculates the answer for you, and THEN AUTOMATICALLY calculates the answer when x is in terms of that number. I am guessing you accidentally did 10[sto] x at one point. You can simply unarchived the x number and everything will be dandy!
