#### Choosing the Right Calculator

When deciding which calculator to use, you need to align your needs with your funding. To do that, we highly suggest you follow the 5 steps below.

**1. Identify Your Demands**

First, generate a checklist of all the functionalities you want your calculator to include. Will you need a high-resolution colour device to easily plot multiple graphs at the same time? How about a powerful processor to process your results? By highlighting as many specifications as possible, you will be able to immediately figure out which calculators are best suited for you and what’s not.[the_ad id=”236″]

For obvious reasons, if you need the calculator to work without an online connection, an online calculator app is not the right alternative for you. On the other hand, if your budget is relatively tight but you need a calculator that can help you with computational physics or advance calculations, an online calculator app might be the only feasible choice.

**2. Make the decision on a Budget**

Traditional handheld calculators can be very expensive. For instance, the Texas Devices TI-84 Plus CE graphing calculator, among the most commonly utilized graphing calculators with a colour display costs around $140, which is not an irrelevant sum of money for a learner.

This is good news because most of the student calculator apps on the internet can be downloaded for free. For those who need a physical calculator, you can borrow one from a friend or a kind dude for the day.

**3. Compare the accessible calculators.**

Once your needs, budget, and calculations are all listed, it’s time to choose a couple of calculators. You should carefully review the specs of the calculator that is being selected before deciding which one to purchase.

Your goal should be to reduce as much as possible the selection of calculators which fit your needs.[the_ad id=”236″]

**4. Watch well-reviewed and demonstrable videos **

You would be amazed by how many types of calculator review you will be able to find on the Internet. There are even Channels on youtube devoted solely to calculators, so you should have no difficulty finding more details about one you might be interested in.

Get to know about the device through a video demonstration or a video review. Just because a calculator looks great on paper does not mean that it will also be easy to use.

**5. Please reconsider your purchase.**

Make sure you actually need a traditional handheld calculator before you purchase it. There is a low probability that an expensive calculator would suit your needs better than an average calculator plus a web calculator app.[the_ad id=”236″]
