24 Game Algebra Edition

Description
For decades, teachers drilled American school children using flash cards that gave simple arithmetic problems. The advent of inexpensive electronic calculators in the 1970s made it possible to do much routine arithmetic automatically. Flash cards took new forms.
This set of cards teaches elementary algebra. The cardboard cards are printed on both sides with a circle divided into four quadrants; three quadrants have a digit and the fourth an algebraic expression in variables x and y. The goal of the game is to substitute values of x and/or y that are whole numbers between 1 and 9 into the expression . One seeks a number that can be combined by simple arithmetic operations with the three digits in the other three quadrants to reach a total of 24.
According to the instructions, 12 to 24 cards are selected and placed in a pile at the center of a table. A player who sees a solution to the top card touches it. If his or her solution is correct, the player wins the card. Once it is taken, the next card is in play. The combinations on the cards are classed as easy (one white dot), medium (two red dots) or difficult (three gold dots). Once the group of cards has been played, players add up the point value of the cards they have obtained, with one point for each easy card, 2 for medium cards, etc. The set has 24, 48, and 24 of these kinds of cards, as well as an instruction leaflet.
