Welche Zahlenmenge passt zur Ungleichungskette? 27 ≤ x < 32

Schreib jeweils die ersten 5 Vielfachen auf! V(6) = { [blank_start]6[blank_end] , [blank_start]12[blank_end] , [blank_start]18[blank_end] , [blank_start]24[blank_end] , [blank_start]30[blank_end] , ... } V(7) = { [blank_start]7[blank_end] , [blank_start]14[blank_end] , [blank_start]21[blank_end] , [blank_start]28[blank_end] , [blank_start]35[blank_end] , ... } V(8) = { [blank_start]8[blank_end] , [blank_start]16[blank_end] , [blank_start]24[blank_end] , [blank_start]32[blank_end] , [blank_start]40[blank_end] , ... }

Trage die richtigen Stellenwerte ein! Fülle alle Stellen aus (auch die Null) a) 17 205 = [blank_start]1[blank_end] ZT [blank_start]7[blank_end] T [blank_start]2[blank_end] H [blank_start]0[blank_end] Z [blank_start]5[blank_end] E b) 9 281 = [blank_start]9[blank_end] T [blank_start]2[blank_end] H [blank_start]8[blank_end] Z [blank_start]1[blank_end] E c) 24 090 = [blank_start]2[blank_end] ZT [blank_start]4[blank_end] T [blank_start]0[blank_end] H [blank_start]9[blank_end] Z [blank_start]0[blank_end] E d) 2 098 = [blank_start]2[blank_end] T [blank_start]0[blank_end] H [blank_start]9[blank_end] Z [blank_start]8[blank_end] E

Ordne die Zahlen der Größe nach. Beginne mit der kleinsten Zahl! 454 , 444 , 445 , 544 , 455 , 545 [blank_start]444[blank_end] < [blank_start]445[blank_end] < [blank_start]454[blank_end] < [blank_start]455[blank_end] < [blank_start]544[blank_end] < [blank_start]545[blank_end]

Welche Zahlen sind markiert?

Kennst du die Fachbegriffe zur Addition und Subtraktion? 4 + 5 = 9 Die Ziffern 4 und 5 bezeichnet man als [blank_start]Summanden[blank_end]. Das Ergebnis der Addition heißt [blank_start]Summe[blank_end]. 20 - 12 = 8 Das Ergebnis der Subtraktion wird als [blank_start]Differenz[blank_end] bezeichnet. Die Zahl 20 ist der [blank_start]Minuend[blank_end], die Zahl 12 wird als [blank_start]Subtrahend[blank_end] bezeichnet.

Trage das richtige Zeichen ein! < , = , > a) 4 + 7 [blank_start]=[blank_end] 18 - 7 b) 12 + 12 [blank_start]<[blank_end] 4 . 7 c) 40 : 2 [blank_start]>[blank_end] 6 . 3 d) 28 + 14 [blank_start]=[blank_end] 6 . 7 e) 13 + 8 [blank_start]<[blank_end] 50 - 20 f) 5 : 1 [blank_start]>[blank_end] 18 : 6

Ergänze die fehlenden Ziffern!

Ermittle alle Teiler der folgenden Zahlen! T(6) = { [blank_start]1[blank_end] , [blank_start]2[blank_end] , [blank_start]3[blank_end] , [blank_start]6[blank_end] } T(7) = { [blank_start]1[blank_end] , [blank_start]7[blank_end] } T(8) = { [blank_start]1[blank_end] , [blank_start]2[blank_end] , [blank_start]4[blank_end] , [blank_start]8[blank_end] } T(9) = { [blank_start]1[blank_end] , [blank_start]3[blank_end] , [blank_start]9[blank_end] }

Ermittle alle Teiler der folgenden Zahlen! T(6) = { [blank_start]1[blank_end] , [blank_start]2[blank_end] , [blank_start]3[blank_end] , [blank_start]6[blank_end] } T(7) = { [blank_start]1[blank_end] , [blank_start]7[blank_end] } T(8) = { [blank_start]1[blank_end] , [blank_start]2[blank_end] , [blank_start]4[blank_end] , [blank_start]8[blank_end] } T(9) = { [blank_start]1[blank_end] , [blank_start]3[blank_end] , [blank_start]9[blank_end] }

Ergänze das Zauberquadrat. Die Ziffernsumme (waagrecht, senkrecht, diagonal) ist jeweils 18.
