Best Calculator for the PE Exam

Best Calculator for the Professional Engineer's Exam

The final four in this tournament of scientific calculators were these:

  • Hewlett Packard's HP 35s
  • Casio's fx-115 ES Plus
  • Texas Instrument's TI-30XS Multiview
  • Texas Instrument's TI-36X Pro

The factors considered and the reasoning behind my final choice are fairly solid. I personally prefer the style and feel of one of the other four. But, my overall recommendation for PE examinees is:

the TI-36X Pro

Number One Reason for Choosing the TI 36X Pro

The primary reason for choosing this model over the other contenders is the availability of free instructional video for the TI 36X Pro.

And, there is also a full set of videos available for access through ppi2pass.com. If you purchase a book published by PPI from their site, you get a 5% discount with the ppi2pass discount code. (I keep it updated at the other end of the link.)

The reasoning is this: You can have the best functionality in the world available at your fingertips. But, if you do not know how too use it's capabilities, you are at a disadvantage. Each calculator is unique. Even models in the same series or brand line differ from predecessors in important ways.

Instruction on the model you will use is a valuable plus in choosing the best engineering calculator for the PE exam.

TI-36X Pro User's Guide

I compiled links to the user's guides and operations manuals for all the viable options for the PE exam, from Casio, HP, and TI at the bottom of my article PE Exam Calculators. The TI-36X Pro Guide Book is linked from there.

My Personal Best Calculator for the PE Exam

My own first choice, based on personal preference, is the Casio fx-115 ES Plus.

I prefer the satin metal finish. The two orange keys break up the visual field and provide a reference point for locating function keys. For engineers and exam takers, looking left and right to papers and then to calculator, quickly locating the desired keys on the calculator is a requirement.

The fx-115 ES Plus has a menu similar to the TI 36X Pro, which TI developed in order to compete with Casio's fx-115 line of scientific calculators.

One important caveat: This Casio is of light-weight construction, like a TI. On even ground against the TI in this regard, it yields some comparative favor to the HPs, which are heavier, and to the fx-115W, which is heavy. Additionally, HPs and the fx-115W both are very sturdy. The 115W is flat so it doesn't move around when the keys are furiously mashed and pecked during timed exams. But, the fx-115 ES Plus has 4 small protuberances, one near each corner. This makes it less stable- especially when working on top of a collection of books and papers.

For California examinees, the degree-minute-second key will come in handy on the Civil Surveying exam.

I bought a Casio fx-115W S-V.A.P.M. for the FE, and also used it on the PE exam. I still use it daily in my engineering business. The ES-Plus is the top model, currently.

Another Reason to Recommend the TI 36X Pro as the Best Calculator for the PE Exam

Most recent engineering graduates are familiar with TI-89's and TI-90's. They are comfortable with the navigational functionality of TI's menus.

Because they already know it, most examinees will have an accelerated learning curve to adapt from a TI-89 to a TI-36X Pro. This means hours saved to work problems.

If not for the availability of both free and pay for use instructional video to augment the TI-36X Pro, and the familiarity many have with TI functionality, I would recommend the fx-115 ES Plus.

In many other ways, the two models are similar. But, the TI 36X Pro seems to the best engineering calculator for the 2015 NCEES PE exams (from what is available from Texas Instruments and allowed in the exam room.)

Texas Instruments TI-30XS Multiview vs TI-36X Pro

The primary advantage of the TI-30XS Multiview is integrated into the model's name- it has 4 lines of display. You can scroll through previous entries, see the equation you input, and modify data to derive new answers. It is a CAS calculator, solves derivatives, and solves calculus problems (with definite results).

The TI-36XS Pro does all those things, even the 4 lines of visual text on the display.

The TI-36X Pro is a kind of hybrid TI-30XS meets fx-115. The offspring is not a monster, though. It is an excellent tool, and my recommendation over all other TI models on the NCEES list of permitted calculators.

HP 35s- the key layout and key response are second to no other calculator on the NCEES approved calculator list.

Best HP Calculator for the PE Exam

TI-36X Pro vs HP 35s

The primary difference in these two calculators is the mode of entry. HP is, of course, a Reverse Polish Notation entry calculator. I learned calculators on my father's HP collection. So, this is very natural to me.

Years of surveying and using an HP-48, and my HP-38 in college have taught me RPN like second nature. I now use a Casio desk calculator (an fx-115), and there are some advantage to using RPN.

Something I like about HP calculators is their attention to the detail of feel. The best factor, of course, is the diverse functionality available in the HP 35s.

On Amazon, after hundreds of reviews, the TI-36X has 4.6 of 5 stars. The HP 35s has a 4.1 score out of 5. Though we can't determine exactly what makes the average TI review 10% higher than the average rating for HP, we can understand that the TI-36X Pro has a distinct edge over the HP 35s.

        The price, features and algebraic entry that is identical to Ti's graphics calculators makes the Ti-36 pro a more popular and wise choice for the majority of PE and other calculator users who are not allowed a graphing calculator. It has ALL the functions and features of the Hp 35s aside from an RPN mode and real programming. It makes up for this with a $20 price and a damn good solver that can function as a poor man's programming tool.

        .

        Advantages of the Hp 35s are that it IS programmable, not just a solver and a dual entry RPN or algebraic entry selection. The keyboard is designed for an RPN user though ie awkward to use this as an algebraic calculator. At $50 it is over 2x the cost of the Ti-36 pro.
