TechCalc+ supplies everything you need for a scientific calculator on your smartphone. Users have all the functions to keep themselves at work, even if they are in outside, not stay with their accurate calculator. I know an app like this is just a temporary solution, but this one is worth using.

THE “SWISS ARMY KNIFE” OF SCIENTIFIC CALCULATORS

If you know, you know, the “Swiss Army Knife.” It is the best handful knife for all purposes. You buy them once, and then you can use them under all circumstances. TechCalc+ is the same as that kind of knife. With just one tap, users can do all formulas in one place.

ALL EXPRESSIONS ON THE SCREEN

TechCalc+ shows both the full expression and the running total like the pro-calculator. It is the basic and the best feature of the calculator app. While studying, students must put the numbers and formulas into a line and let the calculator works. But if the result was wrong, they need to check it out. It is easy for everyone to figure out the mistake and fix it with the expressions. And then, the total will change immediately; you just wait till the answer is right.

MANY DIFFERENT CALCULATION MODES

As I said, the “Swiss Army Knife” of Scientific Calculators has all of the needed methods to calculate something. For the students who don’t need advanced calculation, they will focus on the basic mode. But, for the other, who works as an engineer in every field of technologies, some modes like Sci Cal, Hex, Matrices, Complex Numbers,.., must be useful.

GRAPHS MODE IS THE BEST GRAPHIC

For students who will join the exam for university, graphs sure be a nightmare. They try all their best to draw a graph on paper, and something is wrong. All the steps to plot a graph will be automatic with this mode. You just need to put the numbers and formulas in the right place. Make sure, the right place!

Especially with one axis, you can plot up to 7 graphs and see the difference between them. Students can watch the graph as a reference and then draw it on their paper. If they don’t have enough time, just download it. It is effortless for them to download the graphs in PDF format. Last but not least, users have the ability to make a 3D surface plot. You can watch it from all angles and see what happens when you change the parameters.
