SOURCE: Non functional keys

HP 48SX and HP 48GX calculators have a membrane which connects between the internal circuit boards. This is a common failure point. The "ON" button is often the first button to go out. The calculator can be opened up can cleaned, but it is a little involved. Forutnately someone has posted pictures and information on what to do.

There is a text file with information. The file is big because of the pictures. Summary: Open the case, bend metal clips holding the circuit boards together. Clean up any dust and the contacts. Reassemble.

SOURCE: ti 84 plus cannot clear or divide HELPPP!

We had one that did the same thing. The retailer we purchased it from advised us to remove the batteries and put fresh ones in, then turn it back on. Ours resolved itself. Hope this works for you. If not, return it to the retailer you bought it from. Could be a lemon.

What are 4 different fractions that are equal to 1 1/2

Hi Anonymous,
You can make equivalent fractions by multiplying or dividing both top and bottom by the same amount, but only multiply or divide, never add or subtract, to get an equivalent fraction.
I've only shown the fraction part of your question as 1 is a whole number.
1/2 = 2/4, or 4/8, or 8/16 or 16/32 or 32/64 & so on.
Going the other way, dividing 2/4 by 2 will give 1/2.
But, only divide when the top and bottom would still be whole numbers, for instance you wouldn't use divide for odd number fractions, for example 1/3 or 3/5 etc.
Trust this helps, best regards Alan

Dividing decimals

What is the problem? Enter one number (decimal or otherwise) press the divide by key and enter the second number. As long as the second number is not equal to zero you get a meaningful result. Try it. No special handling is necessary.

What is the answer to 10x minus 3x equals 20 plus 1 equals what


X = 3 (answer)

Here are the solution steps:

10x minus 3x equals 20 plus 1

10X minus 3X is 7X (right?)
20 plus 1 is 21 (right?)

7X = 21

now divide both sides of the equals sign by 7

7X divided by 7 equals 21 divided by 7

7X / 7 = 21/7

X = 3 (answer)

Dont know how to add or subtract on it

On most calculators you enter operations as you would write then on a line (a single line). This is called algebraic notation.
Say, you wante to calculate 2 +3=?
You turn your calculator on
You clear the screen if is cluttered. (there is a button for that sometines labeled A/C or AC, which stand for Clear All.

You Press the key for number 2 then the key for the plus sign, then the key for 3. You get the result after you press = or ENTER or EXE on Casio calculators. Once you do, that the screen displays 5, the summ of 2 and 3.
Tu summarize (The content of each bracket [] is a key you press.
[2][+][3]= ----> 5 Addition: 2+3=5
[3][x][9]= ----> 27 Multiplication 3 times 9 equals 27
[1][8][/][2]= --->9 Division 18 divided by 2 equals 9
[3][3][-][9]= ---> 24

Hope you will enjoy using your calculator

Program for calculator using vc++

hi, here the code...
class is used for items(item.h) . In this class are stored the two number into property and the result:
property double nr1;
property double nr2;

The operations like :asin,cos,power,pi,plu,divide,sqrt etc. are edited into inherited class from items:

#pragma once
#include "Items.h"

using namespace System;
public ref class asinus : public Items



double^ asin(double a)
return Math::Asin(a);



In the base class 6 boolean variable is used for the precedent operation:

bool plus;
bool minus;
bool produs;
bool divide;
bool sin;
bool prec;
For button equal:

private: System::Void btnegal_Click(System::Object^ sender, System::EventArgs^ e)
prec = false;

if(plus == true)
this->txtRes->Text = Convert::ToString(p.aduna(i.nr1,i.nr2));
else if(minus == true)
this->txtRes->Text = Convert::ToString(m.scadere(i.nr1,i.nr2));
else if(produs == true)
this->txtRes->Text = Convert::ToString(pr.inmultire(i.nr1,i.nr2));
else if(divide == true)
this->txtRes->Text = Convert::ToString(d.impartire(i.nr1,i.nr2));

there is a function for operaton click:
private: System::Void Operation_Click(System::Object^ sender, System::EventArgs^ e) { if(prec == false) { i.nr1 = Convert::ToDouble(this->txtRes->Text); } if(prec == true) { i.nr2 = Convert::ToDouble(this->txtRes->Text); } }

There is no "plus equal" key!

press the plus key again, it should work. ie put a number in and press the plus key twice, it should double, and again it should double again and so on
