what is 3 times 5

Depends what number base you are using, eg: in Octal it is 17 whilst in Hexadecimal it is F.what is 3 times 5
= 3+3+3+3+3
what is 3 times 5
In fact, it is taught both ways, and the most important thing for a student to learn (sooner or later) is that both interpretations give the same answer. (Multiplication is commutative.) There are people who insist that only one or the other should be taught; in my opinion, there are good reasons for each choice as an initial teaching model, so if possible I like to find out what a child has been taught before telling them what it means.The first number tells you how many of the second number are to be added together.
So, 3 times 5 tells you there are three 5 fives to be added together.
Thus, \(\displaystyle \ 3 \times 5 = 5 + 5 + 5.\)
