Sansū 1-nen: Keisan Game (けいさんゲーム さんすう1年 ＋−×÷, "Calculation Game: Arithmetic for First Graders") is the first in a series of arithmetic learning video games for the Nintendo Family Computer. This video game is the prequel to Sansū 2-nen: Keisan Game, Sansū 3-nen: Keisan Game and Sansū 4-nen: Keisan Game.

Summary

File:S1KGscreenshot.png

Answering a mathematical question incorrectly causes negative consequences in Sansū 1-nen: Keisan Game.

This particular game focuses on the basics of addition (たしざん) and subtraction (ひきざん).

As a retro video game primarily meant for educational purposes, there is very little variety between the four modes of the game. Half of the modes are for addition while the other half is for subtraction. These modes each contain short mini-games where the player have to solve the displayed math problems. Even though this game is educational, players can only incorrectly guess five times before the player is forced to "die" and is assigned a game over message.

This methodology of learning replicated the "sink or swim" philosophy of teaching and would be used in the later games.

Sansū 2-nen: Keisan Game (けいさんゲーム 算数2年 ＋−×÷, "Calculation Game: Arithmetic for Second Graders") is the second in a series of arithmetic learning video games for the Nintendo Family Computer.

Summary

Successfully completing all the math problems results in positive reinforcement, like finishing a robot in a factory, for example.

Unlike the first game in the series, the core focus of this video game is on addition (たしざん). More advanced versions of subtraction (ひきざん) and multiplication (かけざん) are also to the mix in order to teach all four basic functions of arithmetics.

Intended to be an educational retro video game experience, there is little variety to this video game. Variations for one-player (ひとりでやる) and two-player (ふたりでやる) games are included. Even though this game is educational, players can only incorrectly guess five times before "dying" and given a game over message. This methodology of learning replicated the "sink or swim" philosophy of teaching.

Math problems included with this game allow players to play on a golf course (but with slightly different rules than the actual golf game), as a worker in a robot factory, and to fill the multiplication table full of basic multiplication facts.

Sansū 3-nen: Keisan Game (けいさんゲーム 算数3年 ＋−×÷, "Calculation Game: Arithmetic for Third Graders") is the third in a series of arithmetic learning video games for the Nintendo Family Computer.

Summary

File:Sansu3nenKeisanGameDividingby0.png

In this screenshot, the player has to divide by zero, which usually results in an error message on most calculators and computers.

The core focus on this video game is exclusively on multiplication (かけざん) and division (わりざん). No addition or subtraction facts are taught in this game. Primarily meant for educational purposes, there is little variety in this retro-gaming experience.

Four modes are utilized, two for multiplication and two for division. These game modes contain short mini-games where solving the displayed math problems correctly results in positive feedback. The division rounds allow players to control a submarine while the multiplication rounds allow the players to become space cadets and car drivers. Only five incorrect answers are accepted before the game prematurely ends. Dividing by zero appears to be expected by the player in the game; simply resulting in an answer of zero.

Variations for one-player (ひとりでやる) and two-player (ふたりでやる) games are included with all the four modes of play.

Sansū 4-nen: Keisan Game (けいさんゲーム 算数4年 ＋−×÷ Calculation Game: Arithmetic for Fourth Graders) is a Family Computer educational video game that was released on October 30, 1986. This video game serves as a sequel to sequel to Sansū 1-nen: Keisan Game, Sansū 2-nen: Keisan Game, and Sansū 3-nen: Keisan Game.

Summary

File:Sansu4nenKeisanGameDivisionLevel.png

Avoiding the ghost and progressing to the next door in order to solve another division problem.

This video game is an educational video game teaching four basic principles: division, adding/subtracting decimals, adding/subtracting fractions and multiplying/dividing decimals. Each mini-game has two difficulty levels and allows for two players to take turns playing the mini-games.

In the "Division" and "Decimal Addition & Subtraction" challenges, players have to control a man as he tries to destroy monsters inside a dungeon with a sword. An unbeatable ghost runs outside the building; he cannot be defeated with the sword and will instantly defeat the character if touched. Climbing to the top of the building naturally results in more math questions being asked. The other challenges result in having to control a race car as it navigates through a complex labyrinth. Players must find the exit tile while avoiding rival drivers in order to access the next math question.
