Goukaku Boy GOLD - Shikakui Atama o Maruku Suru - Keisan no Tatsujin — About this game
Work through calculation problems covering whole numbers, decimals, fractions and units. The challenge is to choose a sound method, carry out the arithmetic and commit an answer without overlooking a sign or conversion.

Revisit the same kind of problem if the method still feels uncertain.
