The Clear-key clears the display, operands, and functions from memory. The keyboard "accelerator or hot" key for the clear key is "c".
"<-" Key is the backspace key. The backspace key allows you to backspace on numbers being input to the display. It does not work on result displays. Any display content can be edited with the display edit functions which are activated by right-clicking on the display. The keyboard "accelerator or hot" key for this function is the keyboard backspace key. The "1/x" key takes the inverse of the value in the display. The "accelerator or hot" Key for this function is "x".
The "%" takes the percentage of the value in the display or in other words it multiplies the number by 0.01. The keyboard "accelerator or hot" key for this function is "p". The square root key takes the square root of the displayed number. The "accelerator or hot" Key for this function is "q".
The "pi" key inputs the constant pi into the display. Pi is set to 3.14159265358979. The keyboard "accelerator or hot" key for this function is "i". The "=" key is used to total or subtotal calculations. The keyboard "accelerator or hot" key for this function is "=". The log-key is used to take the base 10 log of the number in the display. To take the inverse log of the displayed number press the "inv" key. The log-key will change to a red "10 to the X" key to signify inverse log or 10 to the number input power. The keyboard "accelerator or hot" key for this function is "g".
The ln-key takes the natural logarithm of the displayed value. To take the inverse natural log or (e to the x power) press the "inv" key. The ln-key will change to a red (e to x power) key. The keyboard "accelerator or hot" key for this function is "l". The "x squared" key is used to square the number in the display. The inverse square or square root can be taken using the inverse key to switch this key to the inverse mode or by using dedicated the square root key. The keyboard "accelerator or hot" key for the "x squared" key is "a".
The "e to the 0.000" key is the scientific notation key. It places the number in the display into scientific notation. A second input value is required after this key is pressed to set the exponent to the base 10 part of the scientific notation. The inv key will convert the scientific notation representation of the number back to a floating point notation. In cases where the scientific notation number may be too large for floating point, the number may remain in scientific notation. The keyboard "accelerator or hot" key for this function is "e".
The "y to the x" key takes the input value to the x power. After this key is pressed a second number is input for the exponent value. The inv key will take the "xth root of y". The first input value is the base and the second input is the xth root. The keyboard "accelerator or hot" key for the "x squared" key is "y".**Calculator Controls** To Top of Document

The MS-key is used to store the current number in the display into memory. The MR-key is used to recall the number stored back to the display for use. There is no memory clear key since its not really required. To store a new number in the memory just click the MS-key and the new number is stored and the previous number is overwritten. The keyboard "accelerator or hot" key for the MS-key is the "s" key, for the MR-key its the "r" key.
The Subfunction Parenthesis allows you to perform a subcalculation enclosed within parentheses without effecting the current operand and function. For example in this equation,
**3 * (6 + 4) = 30** , the display would total the function within the parenthesis showing a subtotal of **10** when the close parenthesis key is pressed and would apply the previous operand and total (**3 * **) to the equation when the "=" key is pressed resulting in a total of **30**. The keyboard "accelerator or hot" key for the open parenthesis key is the " ( " key, for the close parentheses key its the " ) " key. Baby Scientific supports two levels of parenthesis.
The inv key is used to change to the inverse mode for the log, exponent, scientific notation, and trigonometric keys. When in the inverse mode the inv key is changed to red text as are the inverse function keys (press the "View Inverse Mode" button above for a view of Baby Scientific in the inverse mode). The keyboard "accelerator or hot" key for inv key is "v".
The sin key, cos key, and tan key, gives the sine, cosine, and tangent of the number in the display respectively. To take the inverse sine, cosine, or tangent press the "inv" key. The sin, cos, and tan keys will change to red sin to -1, cos to -1, and tan to -1 keys. The keyboard "accelerator or hot" key for these function are "n" (sin), "o" (cos), "t" for (tangent).

**Calculator Operation** To Top of Document

- Baby Scientific can perform chain math functions like an adding machine or business calculator. In this mode each time a new function is pressed the previous operation is totaled. For example 2 + 3 * 4 = 20, each operation is performed as it is input. You can also press the "=" key to total as you perform calculations. Baby Scientific can also perform operations according to order of precedence (default mode). In this mode multiplication and division have precedence over addition and subtraction. For example 2 + 3 * 4 = 14 in this mode because the multiplication has precedence. To change modes select or deselect the "Use Order of Precedence" menu item under "Settings".
- Some functions are single operand functions and the operation is performed on the number displayed immediately. These operations include 1/x, square root, percentage, x squared, conversion to floating point from scientific notation, and trig functions.
- Some functions require two operands to complete the calculation. These operations include, +, -, *, /, "y to the x", and conversion from floating point to scientific notation.
- The maximum positive floating point number supported is 1.78 e +308. The minimum floating point number supported is 2.225 e -308.
- Results are calculated to a maximum of 15 digits of resolution/precision. Values with a higher digit count can be input into the calculator, but calculations are limited to 15 digits.
- There is no clear entry (CE) key on Baby Scientific because its not necessary. The display supports full edit capabilities and clipboard operations such as cut, paste, copy, delete. Just right click in the display to enable these functions. You can highlight numbers with the mouse and edit them in the display. You can copy numbers from other programs and enter them directly into the display or copy results from the calculator into other programs.
- The precision of floating point numbers can be fixed at 2, 4, or 6 digits by selecting the Settings menu and then selecting Resolution.

**File****Exit**- Exits the program, same as the Close box.

**Settings**- Setting selections are saved in the Windows Registry and stay in effect until changed**Resolution**- Resolution->00.xx(2) - Sets the floating point format to an accuracy of 2 decimal places.
- Resolution->00.xxxx(4) - Sets the floating point format to an accuracy of 4 decimal places.
- Resolution->00.xxxxx(6) - Sets the floating point format to an accuracy of 6 decimal places.
- Resolution->Max (up to 14) - Sets the floating point format to maximum accuracy and the number of decimal places is set by the calculation

**Make Topmost Window**- Sets the calculator as the topmost window on the desktop. This allows the calculator to stay in view while your working on another application.**Use Order of Precedence**Selects or Deselects "Order of Precedence" mode. When selected multiplication and division have operation precedence over addition and subtraction. When deselected operations are performed in the order in which they are input.

**Help**- About calculator - Shows revision information and company information
- Help Info - Shows Operation Info and Key Functions. This is a brief help function with information about calculator limitations and definitions of all the function keys. Pressing the function key on the panel will walk-through all of the keys and a description of their functions.
