5 + 5 + 5: How Many Are There?

New York (News) complex scientific questions is common to found dissent and expression around the world, scientists look at these issues, but you are surprised to know that around the world it become an issue that how the answer of 5+5+5+= 15 ?

The first time the case came when American mathematics in third grade children were asked to write a response paper, 5×3 and it was directed that the student will explain why the answer is 15?

A student wrote 5×3 = 15  and state the reason add number 5 by three times, means 5+5+5 is equal to 15.

Children’s reply was declared invalid because the teacher had given the willingness of the 15 constituents of the 5 + 5 + 5, is not wether3 + 3 + 3 + 3 + 3 was write. Based on the answer to 4×6 = 24 and give the wrong reasons the for it.

These questions and deemed them wrong reasons the Internet has been a big controversy.

On the Website on reddit more than 10 thousand people commented on it. Interestingly is that Where many people are blaming the teacher’s wrong decision, there are many who says this decisions that are made is true.

Multiply the sum of three times the number 5 or number should be obtained from 3 to 5 times to obtain combinations, the heated debating on this.

But still not consulted decision on this issue decisively by a great mathematician.
