An electronic record keeping device for recording numerical data under different items. The device has a casing and a memory having a plurality of sections. The number of the sections corresponds to the number of items. Each section has a first memory area for storing a budget data and a second memory area for storing a cumulative expenditures. A key board provided on the casing has number keys for effecting the input of a numerical data, a plurality of item keys for effecting an access to a corresponding section in the memory upon depression of one item key, a mode key for changing the mode between a first mode for entering the budget data in the first memory area, and the second mode for entering the cumulative expenditure in the second memory area. A display is provided for displaying a numerical data inputted by the number keys, and a controller is provided to operate in response to a depression of one of the item keys such that, while the first mode is established, a numerical data as inputted by the number keys is entered and stored in the first memory area as the budget data, and that, while the second mode is established, a numerical data as inputted by the number keys is added to the cumulative expenditure previously stored in the second memory area in the second memory area.

Electronic record keeping device

An electronic learning aid includes a circuit for automatically developing problems, a display for displaying the problems, an input for introducing a calculated answer, and a determination circuit for detecting whether the introduced answer is correct. The display includes a first display unit of plural digits for displaying the problems, and a second display unit of plural digits for displaying the problem number, the score, the correct answer number, and the exercise number.
