Descomposición de sumas hasta 99: ¿V o F?

by Yolanda Janeth Muñoz Robayo
1

Descomposición en decenas y unidades cambia el resultado final de la suma.

2

Descomponer 25 + 36 da 50.

3

Sumar 43 + 56 usando descomposición da 99.

4

La descomposición sólo funciona para números que empiezan por 1.

5

Al descomponer, siempre se deben convertir las unidades en decenas antes de sumar.

6

Si las sumas superan 99, la descomposición ya no se puede aplicar.

7

Descomponer en decenas y unidades facilita sumar hasta 99.

8

Sumar 43 + 26 descompone como (40+3) + (20+6) y da 69.

9

La descomposición separa la suma en decenas y unidades y luego se suman por partes.

10

Para sumar 46 y 28, descompón 46 en 40+6 y 28 en 20+8 y sumas por partes.
