If ever there will be a time in your life (perhaps during the latter part of your academic life) wherein you will need a fraction calculator or a derivative calculator, you might want to remember that such things cost a lot – more than the usual standard calculator. These things come in handy during tests when you do not have access to an online version. Here are some things you need to know about taking care of such an expensive yet useful math tool.
First of all, make it a point to get a protective case for your fraction calculator or your derivative calculator. On days where you know you will not have access to the internet to simply input your computations then copy-paste the answers on a document, your fraction calculator or derivative calculator will have to do. Make sure it does not get banged up in your bag or accidentally scratched by your other things. Just because it is in the bag does not mean it is thoroughly protected; ensure additional Open Calculator protection by getting a small padded case where you can store it.
Second, make it a point to keep fresh batteries in your fraction calculator or derivative calculator even when you do not use it. This is highly important: when months pass by and your battery dries up, you should know to change it lest it leaks. A leaked battery will ruin the fraction or derivative calculator and could even lead to poisoning if you get exposed to it. Having said that, it might be better to just remove the batteries if you know you are not going to use the calculator. Besides, it is very expensive to own one so make sure you take good care of this calculator.
Another thing you can do to take care of your derivative calculator or fraction calculator is to use it carefully. This means no banging on the keys and no slamming it on the table once you take it out to use. While you are not being asked to treat it as if it were a museum artefact, you also cannot get overly playful with it. Tossing it around is a no-no, for a calculator like it (with more high tech mechanisms) are more sensitive compared to those calculators that have simpler functions. It would even be better if you use it on a smooth padded surface when you need it.
Taking care of your fraction calculator or derivative calculator is not that hard given the simple suggestions stated here. However, these things must also not be taken too lightly: failing to do one could definitely do a lot to compromise the condition or quality of your calculator. You might be taking good care of it because you know you will use it once you get out of school and in the work place, or you might be planning to pass it on to another person who will find it useful. Whichever reason, it will definitely be an admirable thing to keep it in pristine condition.
