A la classe de 4t he descobert una nova propietat de la multiplicaci\u00f3.\u00a0 \u00c9s la propietat de dobles i meitats.\u00a0 Aquesta propietat ens diu que si a una multiplicaci\u00f3 a un dels factors fem la meitat i l’altre factor fem el doble el resultat ser\u00e0 el mateix.\u00a0 Aix\u00f2 ens ajuda a simplificar les multiplicacions.<\/p>\n

Per exemple, si tenim la multiplicaci\u00f3 230×16 fent servir la propietat de dobles i meitats podr\u00edem arribar a aquestes situacions: 230×16=460×8=920×4=1840×2=3680×1.<\/p>\n

Aquesta propietat ens pot ajudar a saber els resultats de la taula de multiplicar.\u00a0 Per exemple, 8×9=4×18=2×36=1×72; o 6×8=12×4=24×2=48.<\/p>\n

Espero que apliqueu aquesta propietat tan \u00fatil en el vostre dia a dia.<\/p>\n

Aqu\u00ed teniu unes imatges de com va demostrar la propietat a la classe de 4t.<\/p>\n
