Key guide

You can also type numbers and operators. Press Enter to calculate or Escape to clear the expression.

0–9
Enter a digit.
.
Enter a decimal point.
+
Add. Example: 2 + 3 = 5
−
Subtract or enter a negative number. Example: 5 − 2 = 3
×
Multiply. Example: 3 × 4 = 12
÷
Divide. Example: 12 ÷ 3 = 4
=
Calculate the expression. You can also press Enter.
(
Open parentheses. Expressions inside parentheses are calculated first.
)
Close parentheses.
%
Percentage. 200 × 10% = 20; 200 + 10% = 220; 200 − 10% = 180.
AC
Clear the expression. History, memory and Ans are kept. You can also press Escape.
CE
Delete the last character. AC changes to CE while typing. You can also press Backspace.
MC
Clear the stored memory value.
MR
Recall the memory value into the expression.
M+
Add the displayed result or the value of the current expression to memory.
M−
Subtract the displayed result or the value of the current expression from memory.
Deg
Use degrees for angles. Example: sin(30) = 0.5
Rad
Use radians for angles. Example: sin(π ÷ 2) = 1
Inv
Show inverse and alternative functions. The keys return to normal after entering a value or function.
x!
Factorial. Example: 5! = 5 × 4 × 3 × 2 × 1 = 120. Accepts integers from 0 to 170.
sin
Calculate sine using the selected Deg or Rad mode.
cos
Calculate cosine using the selected Deg or Rad mode.
tan
Calculate tangent. Undefined angles, such as 90 degrees, return an error.
ln
Natural logarithm. Example: ln(e) = 1
log
Base-10 logarithm. Example: log(100) = 2
√
Square root. Example: √(9) = 3
π
Enter pi.
e
Enter Euler’s number, approximately 2.71828.
Ans
Recall the previous answer.
EXP
Enter E for scientific notation. Example: 2 EXP 3 = 2 × 10³ = 2000
xʸ
Raise a number to a power. Example: 2 xʸ 3 = 8
sin⁻¹
Shown with Inv. Inverse sine. Example in Deg mode: sin⁻¹(0.5) = 30
cos⁻¹
Shown with Inv. Inverse cosine. Example in Deg mode: cos⁻¹(0.5) = 60
tan⁻¹
Shown with Inv. Inverse tangent. Example in Deg mode: tan⁻¹(1) = 45
eˣ
Shown with Inv. Raise e to a power.
10ˣ
Shown with Inv. Raise 10 to a power.
x²
Shown with Inv. Square the input value.
ʸ√x
Shown with Inv. Find an nth root. Example: 27 ʸ√x 3 = 3
Rnd
Shown with Inv. Enter a random number from 0 (inclusive) to 1 (exclusive).
History icon
Show or hide history. Select a previous result to use it again.
Swap arrows
Swap the calculator and history panels. On smaller screens, their vertical order is swapped.
Resize handle
Drag left or right to adjust the history and calculator widths. You can also use the left and right arrow keys. Double-click or press Enter to restore the original width.
