## What is Scientific++?

Scientific++ is a scientific calculator which has the following additional functionality compared with most available calculators: 

- Shows the expression as you enter and keeps a history of your calculations (Swipe up on the screen to reveal the history)
- Capability of performing fraction manipulations and converting between different formats (proper, improper, and mixed fractions) and seamless integration of fraction, integer, and decimal manipulations. 
- Capability of inputting degrees, minutes, and seconds for angles and converting between degrees-minutes-seconds format and decimal format.
- Capability of calculating permutation,  combination, Least Common Multiple (LCM),  Greatest Common Divisor (GCD), and prime factorization. 
- Quadratic and system of two linear  equations solver 
- Rectangular to polar and polar to rectangular coordinate conversion (extremely useful for phasor calculations for electrical engineers)  
- Common physical constants can be chosen from a list and used in the calculations. 
- Throws a set of dice (choice of 1 die to 4 dice)
- Backspace to delete last digit entered.
- The left pane scrolls to reveal more functionality without a need to switch modes. The digits and most common operations are always visible and the less common operations can be revealed by scrolling the left half of the screen.
- Sinusoidal functions can be calculated for angles in units of degrees, radians, or gradians. 
- Showing the content of memory on MR button, as long as it fits.
- Right Triangle & Rectangle Calculator through in-app purchase. 

Scientific++ is an ongoing project and we are working on more features and functions to be added to every update of the app.

You are going to love the simplicity of the user interface and you will get used to the extra functionality added to this product.

### 1/5 — Scientific not working

*2024-08-29*

Scientific not working

**Developer response:** Please let us know what functionality you are looking for and we will walk you through the steps. You can email us at calc@dogahe.com. All the functionality that you see in the app description should be working. So we are surprised by your message. We hope we can help you find what you are looking for.

### 2/5 — Very confusing

*2023-04-18*

I am use to using Casio and TI. Entering the data and getting results is very confusing.
Casio especially is much easier. I will stick that. Glad I only paid $6 for this bundle.

**Developer response:** Thanks for your feedback. We tried to be consistent with many mainstream calculators as far as the order of button presses. We believe most of the order of operations are pretty straightforward and logical. Please let us know which operations are confusing to you?

### 1/5 — Ripoff

*2019-04-12*

This is NOT GOOD for a 4 year old. Trying to use the calculator will confuse any user so much they will forget what they were trying to do. Shame on you.

**Developer response:** The age rating of the apps are not assigned by the developers. The developers answer a series of questions and Apple determines the age rating. The age rating of this calculator is determined to be 4+ which is exactly the same as the age rating of Apple’s calculator app and many other utility apps. I understand you feel this calculator is not appropriate for a 4 year old but personally I do not give an iPhone to my 4 years old to be even worried about which apps he or she is using. I don’t think I ever touched a smart phone or a calculator before I was 9 or 10 years old.

### 5/5 — It may not be pretty

*2018-04-19*

But brains are better! This is a hidden gem that deserves a closer look. So many scientific calculator apps get it almost right but fail miserably where it counts. This one nails it.

### 5/5 — Awesome App!

*2018-01-08*

Great functionality! Fraction calculations, degrees minutes seconds conversion and equation solvers, couldn't find these in a single app elsewhere. And now a right triangle calculator with some cool graphics, great work.

### 5/5 — Great calculator

*2013-01-12*

The conversion from degrees minutes seconds to decimal comes very handy among other features like fractions and quadratic equations, all of them very unique to this all around calculator. The colors are very vibrant too.

### 5/5 — Best for me

*2012-11-13, version 1.27*

Innovative ideas
Specially for transformation in minutes degrees and seconds.
Also good in probability applications
Simple and useful

### 5/5 — Excellent

*2012-08-18, version 1.26*

Best calculator offered in the app store.. Great buy at 1 dollar

### 5/5 — Awsome!!!

*2012-08-09, version 1.26*

I used it in my exams and i got A! Thanks to Dr Dogahe!

### 5/5 — Best buy

*2012-07-08, version 1.26*

Amazing, all college, even high school students should have this app!
