Evaluating 2^8 returns 256, while √144 returns 12.

Factors That Affect the Result

Angle mode, operator precedence, rounding and domain restrictions can affect advanced calculations.

Frequently Asked Questions

Does angle mode matter?

Yes. Trigonometric results differ between degrees and radians.

Can every expression be evaluated?

No. Some inputs fall outside valid mathematical domains.

Are results rounded?

They may be displayed to limited precision.

Scientific Calculator Usage Tips

This calculator is designed for calculations that go beyond basic arithmetic, including powers, roots, logarithms and trigonometric functions. Check whether your angle setting is degrees or radians before using sine, cosine or tangent, because the same input gives different results in each mode. Use parentheses to control the order of operations in longer expressions, and keep intermediate values unrounded when accuracy matters. For complex formulas, calculate one logical step at a time so errors are easier to spot.
