The discussion centers on the debate about whether multiplication is merely repeated addition. While some argue that multiplication should be viewed as a distinct operation separate from addition, others believe that teaching it as repeated addition is beneficial for early learners. The conversation highlights that multiplication can be generalized beyond integers, particularly in higher mathematics, where operations like matrix multiplication do not align with the repeated addition concept. Critics of the repeated addition view assert that it becomes less applicable with rational and real numbers, as well as in practical applications like calculating area. Ultimately, the dialogue emphasizes the importance of understanding multiplication's broader implications while recognizing its foundational role in early math education.

That's pretty disrespectful of the young.

The average youth unemployment rate (through no fault of their own) currently stands at 25% and reaches over 50% in some areas.

Those who do get jobs do so, not on their academic record but by knowing the rich and powerful, if recent news articles are to be believed.

go well

I think that multiplication is the unique operation which satisfies the distributive property, and, when applied to integers, is equivalent to repeated addition.

try to multiply e by pi. e from exponential 1 and pi = 3.14...you'd see it's not a repeated addition at all.

I think it is...add e to itself 3 times, then add some more 'stuff'
