正整数

正 = 一 + 止 : Mnemonic symbol: a stick-figure with straight lines. James II of England (zh) really has to use the engine's bathroom ((e)ng4), but there's a stick-figure (正) blocking the stalls with a barrier (止). The stick-figure measures with a flute (一) whether James is tall enough to go. James stands very straight (正) to make himself as tall as possible.

整 = 敕 + 正 : James II of England (zh) has been the guardian of the engine for a long time. One day a stick figure (正) shows up with the imperial order (敕) to renovate the engine and make a fuel cell electric drive out of it. James II of England can only watch in horror as the stick figure starts overhauling the engine's living room ((e)ng3).

数 = 娄 + 攵 : Sheldon Shrimp (shu) occupied a lunar mansion (娄) inside of the space station (Ø3) although he knows that it is to be torn down. Outside of his lunar mansion the construction (or rather destruction) workers are already counting (数) down from ten. When they count (数) zero, they will start taking down the whole thing with their sledgehammers (攵).
