   • Use the numeric buttons (0–9) to enter numbers.
   • Select arithmetic operations (+, -, ×, ÷) for basic calculations.
   • Press = to display the result.
2. Perform Trigonometric Calculations
   • Switch between DEG or RAD mode using the toggle button, depending on whether the angle is in degrees or radians.
   • Use sin, cos, or tan buttons to calculate trigonometric values.
3. Calculate Powers and Roots
   • Use x² to square a number or x³ to cube it.
   • Press √x for square roots or input numbers with xⁿ for custom powers.
4. Logarithmic Functions
   • Use log for base-10 logarithms and ln for natural logarithms.
5. Factorials and Reciprocal
   • Press n! to calculate factorials (e.g., 5! = 120).
   • Use 1/x to calculate the reciprocal of a number.
6. Clear and Backspace
   • Press C to clear the entire display.
   • Use the backspace (←) button to delete the last digit or operator.
7. Parentheses for Complex Expressions
   • Use ( and ) to group parts of an expression for calculations with multiple operations.
8. Constants
   • Use π to insert the value of pi (3.14159).
   • Press e to use Euler’s number (2.71828).
9. Equal Sign and Results
   • Press = after entering an expression to see the result on the display.
10. Memory and Previous Answer

• Use the Ans button to recall the last result for new calculations.

This calculator supports both basic and advanced operations, and all inputs are displayed on the larger, user-friendly screen for easy review.

About the Scientific Calculator

Math was never my strong suit growing up. In fact, I failed it more times than I’d like to admit. It wasn’t that I didn’t try—I just never had the right tools or guidance to make sense of the numbers. Back then, calculators felt intimidating, and most of the time, I didn’t even know where to start. The frustration only grew, and eventually, I walked away from it altogether.

Years later, when I decided to pursue my GED, math was still the hurdle I dreaded most. I needed something simple, something that could help me learn without feeling overwhelmed, especially with time limits on math tests. That’s when I started experimenting with calculators again, but I still found many of them too complicated or cluttered. I knew I needed a tool that could break problems down and help me focus on the basics. Slowly but surely, with patience and the right setup, I started to rebuild my confidence in math.

This scientific calculator is built with that experience in mind. It’s designed to be simple enough for beginners while offering all the functions needed for advanced calculations. I was inspired by the Desmos Scientific calculator and therefore created this one.

If you’ve struggled with math like I did, I hope this calculator can give you the same sense of progress it gave me. Sometimes, it’s not about mastering everything all at once—it’s about taking that first step. This calculator can be used by anyone no matter how good in math you are.

Final Thoughts

If you’re like me and math has always felt like a roadblock, I want you to know that it’s never too late to turn things around. With a little effort and the right resources, you can tackle even the problems that once seemed impossible.

This scientific calculator is a small part of my journey, but it made a big difference. I hope it can be the same for you—a reliable tool to help you grow your confidence and reach your goals. Every small step counts, and you’re already on the right track by taking this one. Share it with your school friends far and wide.
