Expression execution order

The investment analysis adds new input at the bottom of the tape and runs expressions from top to bottom. To delete an item from the tape, hover the mouse pointer to the left of the variable or constant name to delete. When you see the (x) icon, click it to delete the line from the calculator.
To change the position of a line on the paper tape, move the mouse pointer next to the result and click the up or down widgets. The investment analysis uses the 10th percentile, the mode, and the 90th percentile of the last line on the calculator tape as the low, likely, and high estimates for the model. To see all values, hover the mouse pointer over the result value on the paper tape.
Expression order

By default, if the tape contains no errors, the calculator automatically recalculates the simulation values and graphs the NPV results for up to 10,000 samples as you edit. To create a smoother NPV curve, select larger sample sizes from the drop-down menu. To manually control the simulation, select and clear Auto recalc or Graph results. When parse errors occur or when the simulation fails because of undefined variables, the calculator displays a red "i" near the result field. You can get more details about an error by hovering the mouse pointer over the “i.”
