542 + 8 = 550
The result of adding 542 plus 542 is equal to 1084.
6401/8>542+258
3 + 542 = 545 - 6 = 539.
-81 + 623 = 542
1084
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").
Add 2.
The positive integer factors of 542 are: 1, 2, 271, 542
Each tile covers a square foot. So you need 542, plus some for spoilage and cutting.
1, 2, 4, 8, 271, 542, 1084, 2168
1 and 542 and 273 and 186 and 9So 8
the answer is 56
