Frequently Asked Questions
What is the difference between DEG and RAD mode?▾
DEG (degrees) measures angles on a 0–360 scale used in everyday contexts. RAD (radians) is used in mathematics and physics where 2π = one full circle. sin(90°) in DEG equals sin(π/2) in RAD — both return 1.
How do I use the calculation history?▾
Click any item in the history panel on the right to load that result back into the display. You can then continue with further calculations from that value.
How does the memory function work?▾
M+ adds the current value to memory, M- subtracts it, MR recalls the stored value, and MC clears memory. When memory holds a value, it is shown below the display as "M: ...".
Can I enter complex expressions?▾
Yes — use parentheses to group operations (e.g., (2+3)×4). Use ^ for powers (e.g., 2^10) and EXP for scientific notation. The calculator evaluates standard mathematical operator precedence.
