Use the key to enter the PROP mode when you want to solve a ratio expression.
In PROP mode, you can solve the value of X in the ratio expression.
a/b = x/d | a/b = c/x |

Inputting and Editing Coefficients•The PROP mode lets you determine the value of X in the ratio expression a/b = X/d (or a/b = c/X) when the values of a, b, c and d are known.
•Use the coefficient editor screen to input the coefficients of a ratio expression. The coefficient editor screen shows input cells for each of the coefficients required by the currently selected ratio expression type.
•Rules for inputting and editing coefficients
-Data you input is inserted into the cell where the cursor is located. When you register input into a cell, the cursor moves to the next cell to the right.
-The values and expressions you can input on the coefficient editor screen are the same as those you can input in the COMP mode with linear format.
-Press while inputting data clears your current input.
-After inputting data, press . This registers the value and displays up to six of its digits in the currently selected cell.
-To change the contents of a cell, use the cursor keys to move the cursor to the cell and then input the new data.
•You can clear all coefficients to zero by pressing the key while inputting values on the coefficient editor screen.
