### Fun Facts About the History of Percentage Calculations

The evolution of the scientific calculator is a fascinating journey through technology and innovation, marked by milestones that have significantly impacted the scientific, educational, and engineering communities. Here are some intriguing fun facts about the history of scientific calculators:

**The First True Scientific Calculator:**The Hewlett-Packard HP-35, launched in 1972, is widely recognized as the world’s first handheld scientific calculator. It was called “35” for its thirty-five keys and offered functions like trigonometry, logarithms, and exponential calculations, revolutionizing the way professionals and students approached complex mathematics.**A Pricey Beginning:**When the HP-35 was first introduced, it carried a hefty price tag of $395, equivalent to over $2,400 today when adjusted for inflation. Despite its cost, it was a massive hit among engineers, scientists, and students for its portability and computational capabilities.**From Slide Rules to Pocket Powerhouses:**Before scientific calculators, slide rules were the primary tool for complex calculations. The introduction of portable scientific calculators rendered the slide rule virtually obsolete almost overnight, showcasing the dramatic impact of technological advancement.**Space Exploration:**Scientific calculators have even made their mark beyond Earth. The HP-65, the first programmable handheld calculator, was used during the NASA Apollo missions in the mid-1970s for backup navigation calculations.**The Evolution of Display:**Early scientific calculators used LED displays that consumed a lot of power. The introduction of LCD (Liquid Crystal Display) in the late 1970s and early 1980s allowed for longer battery life and more compact designs, making scientific calculators even more accessible and user-friendly.**The Calculator Wars:**The 1970s and 1980s saw intense competition among manufacturers to produce the most advanced scientific calculators. This era, often referred to as “The Calculator Wars,” drove rapid technological advancements, leading to the sophisticated, multifunctional devices we use today.**Software Emulation:**Today, the functionality of scientific calculators can be emulated on smartphones and computers, providing the same powerful computational abilities without the need for a dedicated physical device. Despite this, many professionals and students still prefer the tactile feel and reliability of a handheld calculator.

The history of scientific calculators is a testament to human ingenuity and the relentless pursuit of making complex calculations more manageable and accessible to everyone.

### Can I calculate both percentage of a value and percentage increase/decrease?

This tool is designed for direct percentage of a value calculations. For increase/decrease, a simple manual adjustment can be applied.

### How do I reverse the calculation (finding the whole from a percentage)?

To find the whole, input the part as the value and the percentage it represents, then calculate inversely.

### Is there a limit to the values I can input?

No, our Percentage Calculator can handle a wide range of values, offering flexibility for various calculations.

### Is this tool free to use?

Absolutely. It’s designed to offer the precision and variety of functions necessary for thorough scientific research and analysis.
