28 divided by 7 is 13

Explain why

No, twenty-eight divided by seven is definitely four, not thirteen.

This equation doesn't seem to work for any integer base.

7 does not go into 2.

7 go's into 8 once with a remainder of 1.

Drop the two and you have 21.

7 go's into 21 3 times. Therefore:

->13

Ok. 7 times 3 is 21.

Ok. 7 times 1 is 7.

Um, we did short/long division in Grade Four. How old are you?

Listen this *is* quite funny. I've seen it before and I had a good laugh out of it. It was rather surpricing to being proven that 28 divided by 7 actually is 13.

But it is very hard to demonstrate this in a ascii forum as this is. And quite hard to understand the reasoning when you try to decipher the attempt.

Trust me, it's funny!

Fiddling with place values, that's all. Although yes, i take your point, it is quite funny fiddling with things like this. I had a lot of a amusment proving that the world was flat, on top of four giant elephants and a turtle. XD

I can make it 21.

Use Roman numerals:

28/7 = XXVIII/VII

Cancel the VII... 🙂

Humorous stuff. He should have had Costello to divide up the actual products...

(Heheh)

Or asked what 7x4 was equal to.

Unrelated question... who here can draw the map from in the Safari book?
