Eine frische Variante der klassischen Zahlenpyramide. Jedes Rätsel ist eine Additionspyramide, bei der jeder Block aus den beiden direkt darunter gebildet wird - doch das Rechenzeichen wechselt von Block zu Block. Mal wird addiert, mal subtrahiert, mal multipliziert, und das Zeichen steht in jedem Block.
Genau das macht aus einfacher Arithmetik ein echtes Rätsel. Weil ein fehlender Block auch unter einem bekannten liegen kann, rechnen Sie rückwärts: Subtrahieren macht ein Plus rückgängig, Addieren ein Minus, Teilen ein Mal. Füllen Sie jeden Block, den Sie aus zwei bekannten Werten bilden können, kehren Sie für den Rest das Zeichen um - und jede Lücke ist auf einen einzigen Wert festgelegt. Sie müssen nie raten: jede Division geht glatt auf, jede Lösung ist eindeutig.
Mit Steigerung. Fünf Stufen führen von kurzen, freundlichen Brettern zu sechsreihigen Riesen: Aufwärmen und Einsteiger bleiben bei Plus und Minus; Gemischt bringt die Multiplikation (und das Teilen, um sie rückgängig zu machen); Alles gemischt bringt alle drei Zeichen ins Spiel; und Gipfel stapelt sechs Reihen mit den wenigsten Hinweisen im Buch.
Dann umgedreht. Ein abschlie endes Kapitel Versteckte Zeichen füllt jede Zahl aus und lässt die Zeichenkreise leer - Sie finden jedes +, - oder × selbst. Dieselbe Pyramidenlogik, rückwärts gedacht. Insgesamt 124 Rätsel.
Das trainieren Sie:
- Umkehroperationen - +, - und × rückgängig machen, um einen verdeckten Block zu finden
- Aus zwei Bekannten arbeiten - Schritt für Schritt nach au en bauen
- Erzwungene Ketten - ein gelöster Block gibt den nächsten frei, bis zur Spitze
- Selbstkontrolle - die Spitze entsteht aus der ganzen Basis, eine fertige Pyramide prüft sich selbst
Freundliches Kopfrechen-Training mit Logikrätsel-Kern - kein langes Rechnen, nur klares Schlussfolgern auf in sich geschlossenen Brettern. Und wenn das Buch nicht mehr fordert, geht es mit den Gratis-Downloads weiter: ein Gipfel-Paket mit 30 zusätzlichen sechsreihigen Pyramiden, ein weiteres Set Versteckte Zeichen mit 30 Rätseln, plus eine Gro druck-Lösung für jedes Rätsel im Buch.
Das ist enthalten:
- 104 abgestufte gemischte Zahlenpyramiden über fünf Stufen
- Aufwärmen, Einsteiger, Gemischt, Alles gemischt und Gipfel - von sanftem Plus-Minus bis zu sechsreihigen Herausforderungen mit allen Zeichen
- Ein Kapitel Versteckte Zeichen mit 20 Rätseln - jede Zahl steht, Sie setzen jedes +, - und × selbst (insgesamt 124 Rätsel)
- Eine klare Anleitung, die Regeln und eine ausgearbeitete Beispielkette vorn
- Eine Seite mit Lösungstipps - jedes Zeichen umkehren, aus zwei Bekannten arbeiten, die Spitzen-Kontrolle
- Gro e, übersichtliche Rätsel mit Platz zum Schreiben auf jeder Seite
- Vollständiger Lösungsteil, Schritt für Schritt
- Drei Gratis-Downloads im Buch (einfach den QR-Code scannen): Gro druck-Lösungen für jedes Rätsel, eine pro Seite; ein Gipfel-Paket mit 30 sechsreihigen Pyramiden; und ein Set Versteckte Zeichen mit 30 Rätseln - alle mit vollständigen Lösungen
Ideal für Jugendliche und Erwachsene - und rechenstarke Kinder: Fans von Kopfrechnen und Logikrätseln, Sudoku- und Denksport-Liebhaber, Mathe-AGs und Klassenzimmer. Eine Lösung, reine Logik - ohne Rechen-Plackerei.
