I did not use my calculator for a while and when I turned it on there are about 5 columns that do not work. When I do the calculation...those 5 column figures are impossible to see. Any advice how to fix this?

Re: 5 column pixels missing

This sounds very much like the conductive rubber strip that is between the LCD display and PCB is not making contact. This can happen if the calculator has been dropped or bent.

Step 1 - locate the column in question - in this case the hundreds column

Step 2 - look at the column immediately to the right of this column

Step 3 - if this number is 5 or more, add 1 to the hundreds column

Step 4 - if this number is 4 or less, do not add 1 to the hundreds column

Step 5 - set all numbers to the right of the hundreds column to zero

Let me know if you have any questions.

Good luck,

Paul

You need to post the question.

To round to the nearest hundredth, you find the hundredths column and look to the column immediately to the right. If it is 5 or more, you add one to the hundredths column. Delete all columns to the right of the hundredths column, and you are done.

Good luck,

Step 1 - identify the column in question - in this case the hundreds' column is the second column, in this case the 5

Step 2 - identify the column immediately to the right of the column above - in this case, the tens' column

Step 3 - if this number is 5 or greater, we add 1 to the column in question - in this case, we add 1 to the hundreds column, making it a 6

Step 4 - if this number is 4 or less, don't add 1 to the column in question

Step 5 - set all numbers to the right of the column in question to 0

I get 9760.

Good luck.

Hi,

Step 1 - identify the thousands column.

Step 2 - look to the number immediately to the right of this column

Step 3 - if 5 or over, add 1 to the thousands column

Step 4 - if 4 or less, don't add 1 to the thousands column.

Step 5 - set all numbers to the right of the thousands column to 0.

In this case, the thousands column is the 7. The number immediately to the right is 0, so we don't add 1 to the 7. We set all numbers to the right of the 7 to 0.

I get 247,000

Good luck.

118+146

Round 118 to the nearest hundred. Look at the number to the right of the hundreds column. If it is 5 or greater, add 1 to the hundreds column. If not, don't add 1 to the hundreds column. Make all columns to the right of the hundreds column 0. Since the number in the tens column is 1, we don't add 1 to the 1 and make the 1 and 8 zeros, so we get 100.

We do the same with 146. 4 is less than 5, so we just change the 4 and 6 to 0 and get 100.

We now add 100 and 100 and get our estimate of 200.

Good luck.

Try squeezing the left side. It that does not work, the calculator may be defective.

Do you mean that some of the pixel columns don't work? As in "empty pixels"? If so, I don't think there is a way to solve this problem, and you can either deal with it or buy a new calculator

It is a display driver issue. You can buy a new one or get it repaired ($100).

How can I fix this? I have to admit I did drop my calculator a couple of times...
