100 x 52 = 5200
100 times 52 is 5200. Break 52 into 50 and 2, multiply each by 100, then add. Because 52 is the week count, 5200 is what a hundred a week comes to over a year.
100 × 52 = 5,200
Adding 100 to itself 52 times gives the same answer.
Splitting 52 to get there
52 breaks cleanly into 50 and 2. 50 x 100 = 5000, then 2 x 100 = 200, and 5000 plus 200 is 5200. It also breaks into 4 x 13, so 5200 is four lots of 1300 if that shape suits the numbers you have.
5200 is a year of weekly hundreds
52 is the week count everyone carries around, so this product is almost always a yearly total: a hundred saved, billed, driven or written every week comes to 5200 over the year. A hundred decks of cards is also 5200 cards, since a deck is 52.
Where the year does not quite fit
52 weeks is 364 days, one day short of a common year and two short of a leap year. Those spare days accumulate, so some calendar years contain 53 weekly paydays and the total lands on 5300 instead. If the rate is daily rather than weekly, the calculation you want is 100 x 365 = 36500.
