Making graphs require intense calculations. If you are searching for a calculator to make the perfect graphs, then this is the perfect catch for you.

Design: The Plus CE uses a rechargeable battery that has made the calculator slimmer for the maker. This model has also been thoroughly revamped and is 30% thinner and lighter than it’s predecessors.

That’s the most significant change you’ll note. The design looks like that of a smartphone, weighing just 7 oz. (200 gm).

The position of the controls is identical to their older version, whereas the controls are smaller and have a (not rounded) rectangular shape giving the calculator a modern look.

There seem to be 46 keys, and almost all have three (standard, blue, and green) functions.

There is no indication of “equals” that is somewhat confusing. If you like to add 2 + 2, instead of “equals”, you press “enter.” The calculator is coated with plastic and can be easily thrown into a bag or backpack.

This hardware is available in white, red, green, purple, light blue, dark blue and grey colours. It’s a lot of them. The business is possibly betting on selling colour.

Battery: All of the TI-84’s previous models had connected wire cells. The Plus CE features another form of contacts used in mobile phones, a removable lithium-ion battery. 

All you need is a mini USB cable (included) to plug it in. Every convenient USB port will do the same as a charger of a car or a device. The hardware will run for a month on a full charge with regular use.

It does have a feature of “deep sleep.” Because of this mode, if it is not in prolonged use, the calculator goes to sleep mode.

Display: The calculator has a 360 pixels wide and 240 pixels tall backlit display. It is nearly HD quality, and it is doing a good job. The display can fit up to 26 characters on the screen and down to 10 lines.

The colour display impacts the device’s processing speed, and so this might seem like a downside, but other benefits outweigh it. Most users think a colour display is pointless for a calculator, but it’s incredibly lovely when you see multiple images on a graph.

The high-resolution monitor is ideal for menu graphics, where at the same time a lot of information is shown.

The calculator is capable of storing and displaying images. It is also possible to set any image as the backdrop to the graph.

Processor speed: Between all the TI- 84 calculators, the Plus CE variant has the speediest processor. It may seem distinct in some instances, though. It relies on the calculator having a multi-pixel colour screen.

If you do a task involving internal processing, and the system can process the data very quickly. It lasts a few seconds, of course, but during exams, each second matters.

Accessible Applications and Functions: The Plus CE has a couple of standard applications such as tables, graphing, matrices, and lists. You will discover a lot of other useful features that you might not intend to see if you click the “apps” key.

The apps included are CabriJr (geometry), Finance (basic), Prob Sim, Periodic (table), Conics, PlySmlt2, Transform (dynamic graphing), Inequalz, and others. 

Another feature noticeable is that this calculator has MathPrint. Hardware can print expressions that appear as written in or by hand in math textbooks (express calculations using templates).

This device can also refine fractions (if they do not have complex operations), but radicals can not be simplified.

Graphing: The calculator does have an upgraded function system that is useful for Calculus students. While you’re graphing, select “piecewise” from the “math” menu and then choose the number of pieces in the function. 

You’ll see a template for filling in a piecewise function. Each graph you draw has a different colour that makes reading easier. You can scroll in through your diagram when you have plotted one, or determine an intersect, etc.

A table feature will assist you to step to a specific “x” value or scroll over it.

Programming: One of Plus CE’s most significant features is its programming capability. You can use programs from the device directly or build your own. You can have them at every point from the main screen.

This calculator’s programming is more straightforward than its previous versions and needs less learning.

Usage: Before purchasing it for a university student, the ability to use a graphing calculator on college exams is an essential factor to consider.

It is okay to use the Plus CE on all major comprehensive college exams. It is permitted on SAT, ACT, PreACT, PSAT, Advanced Placement (AP) Biology, AP Physics, AP Math, AP Chemistry, AP Statistics and other similar tests.
