Abstract
A portable electronic financial calculator and planner displays all the variables associated with the financial problem to be calculated on one screen to enable the user to more efficiently input numeric information corresponding to the various variables of the desired financial calculation. To display all the variables in common English terms, the portable financial calculator and planner has separated the financial problems into separate applications which enables this device to display variables distinct to the selected problem. This portable financial calculator and planner includes a display panel having at least eight lines of multi-digit display units. The portable electronic financial calculator and planner also has an input device which allows the operator to input numeric information into the fields corresponding to the known variables of the financial problem by allowing the user to utilize a movable cursor which is capable of moving from field to field. This input device also includes an answer request symbol to allow the user to assign one variable of the financial problem as the unknown variable to be determined. By displaying all the variables on one screen and allowing the user to input numeric information into any field associated with the variables of the financial problem through the use of a cursor, the portable electronic financial calculator and planner allows the user to operate it without extensive training.
