What the keys do
Use the number and operator keys for arithmetic, parentheses to group operations, and the function keys for sine, cosine, tangent, and square root. Trigonometric inputs are interpreted in degrees. The percent key divides the preceding number by 100, so 200 × 10% gives 20.
The display accepts keyboard input as well. Press Enter or the equals key to calculate. Clear the field to begin another expression.
