About this calculator
A full scientific keypad for trigonometry, logarithms, powers, roots, factorials, and memory storage, built the way you'd type an expression on a real calculator.
Type out a full expression — including parentheses and functions — before pressing "=" to evaluate it, so operator precedence (powers before multiplication, multiplication before addition) is handled automatically. Switch between Degree and Radian mode before using any trigonometric function; results won't match if the wrong mode is selected. The memory keys (M+, M−, MR) let you store a running total separate from the main display and recall it into any expression.
How to use
- Choose Deg or Rad depending on whether your angles are in degrees or radians.
- Tap number and operator keys to build an expression, using function keys (sin, log, √x, etc.) which insert an open parenthesis for you to complete.
- Use x², x³, xʸ, eˣ, and 10ˣ for powers, and ʸ√x, ∛x, √x for roots.
- Press "=" to evaluate the full expression — the result becomes "Ans" for use in your next calculation.
- Use M+/M− to add to or subtract from memory, and MR to recall the stored value.
Tips
- Unclosed parentheses are closed automatically when you press "=", so you don't need to add a matching ")" for every function.
