As I was going to St Ives facts for kids

"As I was going to St Ives" (Roud 19772) is a traditional English-language nursery rhyme in the form of a riddle.

The most common modern version is:

As I was going to St. Ives,

I met a man with seven wives,

Each wife had seven sacks,

Each sack had seven cats,

Each cat had seven kits:

Kits, cats, sacks, and wives,

How many were there going to St. Ives?

Origins

The following version is found in a manuscript (Harley MS 7316) dating from approximately 1730:

As I went to St. Ives

I met Nine Wives

And every Wife had nine Sacs,

And every Sac had nine Cats

And every Cat had nine Kittens

A version very similar to that accepted today was published in the Weekly Magazine of August 4, 1779:

As I was going to St Ives,

Upon the road I met seven wives;

Every wife had seven sacks,

Every sack had seven cats,

Every cat had seven kits:

Kits, cats, sacks, and wives,

How many were going to St Ives?

The earliest known published versions omit the words "a man with" immediately preceding the seven (or nine) wives, but he is present in the rhyme by 1837. A modern understanding of this line suggests that polygamy was a subject of the rhyme, although as it is a nonsense verse, this detail may be nothing more than a metrical device; and simply because they were with the man, it does not necessarily follow that they were all his wives.

There were a number of places called St Ives in England when the rhyme was first published. It is generally thought that the rhyme refers to St Ives, Cornwall, when it was a busy fishing port and had many cats to stop the rats and mice destroying the fishing gear, although some people argue it was St Ives, Cambridgeshire, as this is an ancient market town and therefore an equally plausible destination.

Answers

The traditional understanding of this rhyme is that only one is going to St. Ives—the narrator. All of the others are coming from St. Ives. The trick is that the listener assumes that all of the others must be totaled up, forgetting that only the narrator is said to be going to St. Ives. If everyone mentioned in the riddle were bound for St. Ives, then the number would be 2,802: the narrator, the man and his seven wives, 49 sacks, 343 cats, and 2,401 kits.

This interpretation provided the basis for a verse reply from "Philo-Rhithmus" of Edinburgh, in the September 8, 1779 issue of the Weekly Magazine:

Why the deuce do you give yourselves so much vexation,

And puzzle your brains with a long calculation

Of the number of cats, with their kittens and sacks,

Which went to St Ives, on the old women's backs,

As you seem to suppose? — Don't you see that the cunning

Old Querist went only? — The rest were all coming.

But grant the wives went too, — as sure's they were married,

Eight only could go, — for the rest were all carried.

Owing to various ambiguities in the language of the riddle, several other solutions are possible. While it is generally assumed that the narrator met the man and his wives coming from St. Ives, the word "met" does not necessarily exclude the possibility that they fell in while traveling in the same direction. In this case, there is no trick; just a mathematical calculation of the number of kits, cats, sacks, and wives, along with the man and the narrator. Another possible answer is that the "man with seven wives" might have seven wives, but that none of them were accompanying him on the journey. One way of stating the answer, factoring in these ambiguities, is "at least one, the narrator plus anyone who happens to be travelling in the same direction as him or her". However, still other interpretations concern the phrasing of the question, which might be understood to exclude the narrator. If only the narrator was traveling to St. Ives, but the phrase, "kits, cats, sacks, and wives" excludes him, then the answer to the riddle is zero. If everyone—including those being carried—were traveling to St. Ives, but only the kits, cats, sacks, and wives are counted, then the answer is precisely 2,800.

Rhind mathematical papyrus

A similar problem is found in the Rhind Mathematical Papyrus (Problem 79), dated to around 1650 BC. The papyrus is translated as follows:

A house inventory:

			houses	7
1	2,801		cats	49
2	5,602		mice	343
4	11,204		spelt	2,301 [sic]
			hekat	16,807
Total	19,607		Total	19,607

The problem appears to be an illustration of an algorithm for multiplying numbers. The sequence 7, 7², 7³, 7⁴, 7⁵ appears in the right-hand column, and the terms 2,801, 2×2,801, 4×2,801 appear in the left; the sum on the left is 7×2,801 = 19,607, the same as the sum of the terms on the right. The equality of the two geometric sequences can be stated as the equation (2⁰ + 2¹ + 2²)(7⁰ + 7¹ + 7² + 7³ + 7⁴) = 7¹ + 7² + 7³ + 7⁴ + 7⁵, which relies on the coincidence 2⁰ + 2¹ + 2² = 7.

Note that the author of the papyrus listed a wrong value for the fourth power of 7; it should be 2,401, not 2,301. However, the sum of the powers (19,607) is correct.

The problem has been paraphrased by modern commentators as a story problem involving houses, cats, mice, and grain, although in the Rhind Mathematical Papyrus there is no discussion beyond the bare outline stated above. The hekat was ¹⁄₃₀ of a cubic cubit (approximately 4.8 l or 1.1 imp gal or 1.3 US gal).
