Days of Our Lives - 1965 1-542 was released on: USA: 28 December 1967
I've been looking for an answer to this myself. The closest I can come is that the 542 is just under 4" long (10cm) while the 542/20 is just over 4" long (4 1/8").
2012 - 1470 = 542
1084
The result of adding 542 plus 542 is equal to 1084.
The positive integer factors of 542 are: 1, 2, 271, 542
542 542 or 6969
542 + 8 = 550
542 / 7 = 77.42857
271 x 2 = 542 542 + 542 = 1,084 = 271 x 4
The product of 542 and 10 is 5,420. This is calculated by simply multiplying 542 by 10, which shifts the digits of 542 one place to the left, adding a zero at the end.
