Help! My Sharp EL-531x calculator is not calculating correctly.


First subtract the 106 from the 240, then divide by 800. You need a parenthesis around the first two numbers, then it will work.

HOw to change FSE code on Sharp Advanced D.A.L. EL-531X


Hi there,

To change the FSE code on your SHARP calculator press SETUP and choose 0. FIX means that it shows you all the decimal places. SCI is scientific notation, ENG changes the scientific notation in groups of 3's. NORM1 and NORM2 are your normal number ranges, however norm2 starts from zero and anything negative will be written in scientific notation.

Hi there,

Press SETUP and choose 0 for FSE. Then choose 3 for Norm 1. This will put the calculator back to the original setting.

EL 531X Sharp - Help with calculations


You need a SHARP with Write-View display capabilities. The EL-531X is unable to show that. The Write-View calculators from Shard have a W, example EL-W516 followed by Write-View. Not to be confused with the W in EL-520W
