2

En la suma de tres números siempre se suman las centenas primero.

3

999 + 1 da 999.

4

El algoritmo tradicional añade unidades, luego tens, luego centenas.

5

500 + 500 nunca produce un traslado de diez unidades.

6

En 3º de EGB no se usan llevadas en las sumas.

7

237 + 168 siempre da 405 sin ninguna llevada.

8

En 3º de EGB se trabajan sumas con llevadas.

9

Para verificar, se puede sumar de derecha a izquierda llevando cuando la suma de dígitos es 10 o más.

10

Se pueden sumar números de dos o tres dígitos.

Un ejemplo correcto: 214 + 389 = 603.
