Scientific Calculator
Perform complex mathematical operations with trigonometry, logarithms, and exponents.
Last Updated:
Order of Operations (PEMDAS)
Scientific calculators strictly evaluate mathematical expressions following the standard order of operations to ensure consistent results.
PParentheses (evaluate expressions inside brackets first)
EExponents (powers, roots, and trig/log functions)
M / DMultiplication & Division (left to right)
A / SAddition & Subtraction (left to right)
Manual Step: Evaluating a Complex Expression
Let's evaluate the expression: 3 + 4 × (2^3) - 6
1
1. Parentheses & Exponents
Evaluate the exponent inside the parentheses first.
2^3 = 8
2
2. Expression Update
Rewrite the expression with the evaluated exponent.
3
3. Multiplication
Perform multiplication before addition/subtraction.
4
4. Addition
Working left to right, perform the addition.
3 + 32 = 35
5
Result
Finally, perform the subtraction to get the result.
35 - 6 = 29

The first handheld scientific calculator, the HP-35, was introduced by Hewlett-Packard in 1972. It was nicknamed "The Electronic Slide Rule".
Frequently Asked Questions
What functions does this scientific calculator support?
It supports basic arithmetic, trigonometry (sin, cos, tan), inverse trig functions, logarithms (log, ln), exponents, square roots, factorials, and mathematical constants like Pi (π) and e.
Can I use radians or degrees?
Yes, you can switch between degrees and radians for all trigonometric functions. Click the DEG/RAD button to toggle between modes.
Does it follow order of operations?
Yes, our calculator strictly follows PEMDAS/BODMAS rules: Parentheses, Exponents, Multiplication/Division (left to right), Addition/Subtraction (left to right).
What is the difference between log and ln?
Log (logarithm base 10) is commonly used in scientific and engineering calculations. Ln (natural logarithm, base e ≈ 2.718) is used in calculus, physics, and compound growth calculations.
How do I calculate exponents?
Use the x^y button for any exponent, x² for squaring, or √ for square roots. For example, 2^8 = 256, and √144 = 12.
Can I use parentheses for complex expressions?
Yes! Use parentheses to group calculations. For example: (5 + 3) × 2 = 16. The calculator handles nested parentheses correctly.
