Best TI Calculators

TI-84 Calculator

The TI-84 was released in 1984. It’s predecessor, the TI-83, had been available since 1981. At first glance it looks like a simple calculator with just one button: “Enter” or “Cancel”.

But if you look at the inside of its case, you’ll see that there are some hidden features which make it very useful for many kinds of calculations.

One of these features is the built-in ROM (Read Only Memory). A ROM is a computer chip that stores programs and data. For example, when you type in a number into the keyboard, the CPU reads out what you’ve typed from the RAM and then displays it on your screen.

If you want to change something on your calculator, all you have to do is press a button labeled “RAM”, which will cause the processor to read out the new value from memory.

Another feature is the built-in display. When you’re working on a problem, you may need to see a graph or other graphical representation of your results. You can use the display to check whether you got everything right or not.

Another handy thing is the calculator’s internal memory. With this memory, you can save and load formulas, functions and other mathematical concepts into your calculator so that they become instantly accessible whenever needed.

It took us years to develop this amazing device!

Before you buy a calculator, make sure it has the features above. All of them are necessary for a good education in math. There are many other graphing calculators out there, but none of them have as many great features as the one and only Texas Instruments TI-84!

Best Programmable Calculator


The most common kind of calculator is known as the “programmable calculator”. It can do simple calculations such as addition, subtraction, multiplication and division. It can also do percentages and taxes.

If you need to find the slope of a line, there’s a function for that too! Finally, most programmable calculators come with a graphing feature so that you can create bar charts or line graphs to visualize the data you’ve entered.

In addition to these common features, the best programmable calculator will have many built-in functions that increase its versatility. For a start, it should have a square root button so you don’t have to calculate square roots manually. Next, it’s always useful to be able to take the logarithm of numbers, because sometimes data is stored in logs (e.g.

EE101 or the Richter scale for measuring earthquakes). A calculator with trigonometry functions will also come in useful when you’re taking advanced math classes. If you’re a science student, look for one that comes with physics constants (like the Boltzmann Constant or Avogadro’s Number).

When choosing a calculator, make sure to pick one that’s easy to use. Try it out in the store to see if you’re comfortable with its button layout. It should also have a large display so that you can easily see the numbers you’re working with.
