Degrees or radians
Switch angle mode explicitly so trigonometry never depends on a hidden assumption.
More math.
Less cockpit.
Trig, logarithms, powers, roots, constants, parentheses, memory, and history without turning the calculator into an airplane dashboard.
Calculation history stays on this device. Expressions are evaluated locally and are never sent to a math service.

Scientific calculator questions.
Does the calculator follow order of operations?
Yes. Parentheses and functions are handled first, followed by powers, multiplication and division, then addition and subtraction.
What do DEG and RAD mean?
DEG treats angle inputs as degrees. RAD treats them as radians. The selected mode applies to sin, cos, and tan.
Can I use my keyboard?
Yes. Type numbers and operators directly, press Enter to calculate, and Escape to clear.
Is this appropriate for critical engineering work?
Use it for learning and everyday calculation. Critical scientific, financial, or engineering decisions should be verified with specialized, validated software.
