Why 5x3 is not the same as 3x5?
Al estudiante en cuestión, cuya identidad se desconoce, su profesora le dio por errónea la respuesta a un ejercicio en el que le pedía que se usara la estrategia de la suma repetida para multiplicar 5x3.
El alumno efectivamente respondió que el resultado era "15" y usó en su respuesta la estrategia que se le pedía, incluyendo "5+5+5".
Sin embargo, la maestra dio la respuesta por mala, anotando como la solución correcta "3+3+3+3+3".

Multiplication is an operation different from repeated addition.
"Part of what we try to teach kids is that they are thinkers and problem solvers," said Diane Briars, president of the organization.
"We want students to understand what we are doing and not just have the right answer."

Why?
The question is that the teacher what she asked her students in the statement of the exercise is to show that they know the strategy of repeated addition.
And according to her, the procedure that the student raised was not the correct one.
Multiplying consists of adding a number as many times as another number indicates. So 5x3 (read "five for three") is equal to adding three times the value of 5.

If it is the same, a multiplo for another multiplo will give the same result
Example: 5 Per 3: 15
3 For 5: Da Equal 15
