Great idea for teaching factoring. My students are very confident in their distributing and I never thought to tell them that its undoing that!

Los números primos: disposiciones "geométricas" - Ciencia Bizarra Si disponemos los números en seis columnas nos damos cuenta de que todos los números primos son de la forma 6n−1 o 6n+1 (¡lo cual no quiere decir que todos los números de la forma 6n±1 sean primos!). Es fácil de ver que todos los números de las columnas primera, tercera y quinta son pares y, por lo tanto, compuestos (a excepción del 2, claro). Los de la segunda columna son también compuestos (múltiplos de 3): 6n+3=3(2n+1).
