If it can be done, you need to press SETUP then choose CTRST and use your left and right arrow keys to adjust the darkness of the digits on the screen. Unfortunately, some of the older models do not have this ability so if you do not find that that menu option it means that you cannot do it on the calculator.
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
There is no common logarithm function on this calculator. However, you can calculate it easily enough using the natural logarithm function (ln). The log of x is equal to ln(x) / ln(10). In words, calculate the log of a number by calculating its ln then dividing by ln of ten.
On the back of the calculator, there is a little "reset" hole. Use a pen and press it into that hole for a few seconds, then release. You should now be able to turn on your calculator as if it was brand new from factory without the "p".
It's very simple: the calculators have a default base 10 so that log x it's log x base 10 so here is some logs: log x base y = log x / log y
log (x*y) = log x + log y
log (x/y) = log x - log y Hope it's helped
