Sansuu 5 & 6 Nen: Keisan Game is an educational action game released for the Famicom (NES) in Japan in 1986 by Tokyo Shoseki. Designed to help students practice fifth and sixth-grade mathematics, the game blends arithmetic involving fractions and decimals with arcade-style platforming and racing challenges.
How to play: Use the Arrow Keys to move, and the Z and X keys (which map to the A and B buttons) to interact. Each stage presents you with an equation, and you must navigate your character to the correct answer on screen while avoiding enemies and hazards. Quick thinking is required to balance performing math with standard action reflexes.
Tips: Focus on solving the math problem mentally before maneuvering your character; moving blindly often leads to hitting an incorrect answer or an enemy. In the racing segments, stay near the middle lanes until you spot the correct answer block to minimize your turning distance.
