This is an excellent algebraic calculator. The multiple calculators make in useful for general or specific calculations the most resent changes to the graphing ability greatly enhances the usefulness

I'd tried many good & very good Calculator Apps out there, and I found Technical+ is one of the Best. It is not just a scientific calc, it has built-in variety of extended complex calculation capabilities & references: math learning, financial calc, time calc, unit converters, etc. Maybe the only drawback is the usage of IEC standard in data storage calc, in which 1 Kb is converted into 1000 bytes instead of 1024. • Overall, definitely highly recommended excellent educational product. Thank Youツ

First of all, Hats off to the Dev for creating such a complete calculator app. It's like a Swiss Knife amongst the calculator apps. Very, very useful....

Worth the modest fee. If you are a computer engineer be aware that data storage calculations use the IEC "standard" so 1 kilobyte is converted to 1000 bytes and not 1024 which makes no sense since it not a power of 2/binary number). This will throw off your calculations if you use the actual 1kb=1024 bytes conversion (the practicing standard). I've been a computer engineer for 40 years and have never seen anyone in IT convert 1 kb to 1000. I wish I had the option to not use the IEC values.
