Decimals

(TI-99 - US, Educational)
Released On:
01 Jan 1979
Decimals is an educational game for the TI-99 computer, released in 1970. The story follows a student named Max who attends a school where fractions are being taught incorrectly. A new teacher, Ms. Johnson, arrives and decides to change the way students learn about fractions. She introduces a new method of teaching that focuses on decimals, which is easier for some students to understand.
The gameplay involves solving math problems, first with fractions and then with decimals. The player must input the correct answer, and if they're right, Ms. Johnson congratulates them. If they're wrong, she provides a hint to help them improve their skills. As the game progresses, the difficulty level increases, and the player must apply what they've learned to more complex problems.
