Question 1

How does the mathematical order of precedence work in this calculator?

Accepted Answer

The calculator follows the standard mathematical order of precedence (PEMDAS/BODMAS): brackets first, then powers, followed by multiplication and division, and finally addition and subtraction.

Question 2

What is the difference between DEG and RAD modes?

Accepted Answer

DEG (Degrees) is used for common angular calculations, while RAD (Radians) is the standard unit for scientific and engineering calculations. Switching ensures decimal precision in trigonometric results.

Question 3

How to perform logarithm and exponential calculations?

Accepted Answer

Use 'log' for base 10 and 'ln' for natural logarithms. For exponentials, the tool supports scientific notation via the EXP button and custom powers using the ^ operator.
