Question about Casio FX-115ES Scientific Calculator

Press MODE 4 to enter the BASE-N mode. Press the BIN, OCT, DEC, or HEX button to specify the input number base, enter the number to be converted, then press the BIN, OCT, DEC, or HEX button to convert to that base. To enter the other hexadecimal digits, use the A, B, C, D, E, F buttons (the row of the keyboard beginning with the (-) key.

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

Decimal is base 10 and binary is base 2.

The columns from right to left in base 10 are:

10^10 10^9 10^8 10^7 10^6 10^5 10^4 10^3 10^2 10^1 10^0

Similarly, the columns from right to left in base 2 are:

2^10 2^9 2^8 2^7 2^6 2^5 2^4 2^3 2^2 2^1 2^0

This site does a good job of explaining the conversion from decimal to binary.

For example, take the number 157. The biggest column that goes into 157 is 128, which is the 2^7th column, so we put 1 in that column. Subtracting 128 from157, we get 29. We start all over again. The biggest binary number going into 29 is 16, which is the 2^4th column. When you subtract 16 from 29, you get 13. We start all over again. The biggest binary number going into 13 is 8. Subtracting 8 from 13, we get 5. Biggest number going in is 4, 2^2th column. 1 left over to go into the 2^0 column.

Pulling it all together, we get:

10011101.

Checking, 128 + 16 + 8 + 4 + 1 = 157.

Good luck.

Let me know if you have any questions.

What make and model calculator?

If you want to do it by hand, each hexadecimal digit is four binary digits:

0 = 0000

1 = 0001

2 = 0010

3 = 0011

4 = 0100

5 = 0101

6 = 0110

7 = 0111

8 = 1000

9 = 1001

A = 1010

B = 1011

C = 1100

D = 1101

E = 1110

F = 1111

Press MODE 4 to enter the BASE-N mode. Type in the decimal number, then press BIN to convert to binary. Press DEC to switch back to decimal for the next conversion.

You're limited to numbers in the range [-32768...32767] in binary. You can extend the range if you convert to octal or hexadecimal and then mentally convert each digit to three or four bits.

It is searching for a signal because its signal is so weak it cannot find the base. If it cannot communicate with the base, there is no conversation.

New or not ... your battery is either faulty, prematurely dead or not charging. I am leaning toward not charging ... do you have it plugged into a hot outlet (not switch controlled)? Can you measure the power coming OUT of the transformer? Is there a charging light on the base unit that would indicate a charging condition?

The TI-84 has nothing built-in for base conversion. There are a variety of programs to do this available at http://www.ticalc.org

There're no base conversion facilities built into the TI-83 series calculator. You can download a variety of programs for this from http://www.ticalc.org

You need a binary to hex converter. Go to this link to learn all about it.

Not sure if TI-89 mode keys are the same, but here's the solution for that calculator:

1. Hit the mode key

2. Hit F3 to get tot Exact/Approx (might be different for 89T).

3. Set it to Exact.

4. Take a look at T-89 manual pages 327, 328, 329.

Nice of TI to NOT include that in the manual, huh?

Each of the six phones must have line 1 connected to the same "subscriber loop" (the same phone number). Assuming this is the case, and that you have not assigned any numbers to the the top six speed-dial buttons, each station will have agreed to be assigned a station number.

From any station, pressing the speed-dial button for another station's station number will page that station.

Now, how to properly initiate an intercom conversation differs between announcing to another station that a call is on hold, or a "cold call".
