2 полка 25-18=7

3 полка 25+7=32+185=217

Answer 2

1) 367565 - 285999 * 555 = According to the order of operations (PEMDAS/BODMAS), we need to perform the multiplication first, then the subtraction.

Multiplying 285999 by 555 gives us 158897445.

Subtracting 158897445 from 367565 gives us 208668120.

Therefore, 367565 - 285999 * 555 = 208668120.

2) 999999999 + 1 * 25 = Again, following the order of operations, we perform the multiplication first, then the addition.

Multiplying 1 by 25 gives us 25.

Adding 25 to 999999999 gives us 1000000024.

Therefore, 999999999 + 1 * 25 = 1000000024.

3) На первой полке было 25 книг, на 18 больше, чем на 2, а на 3, на 185 больше, чем на 2 и 1. Сколько всего книг на полке? To find the total number of books on the shelf, we need to add the number of books on the first shelf (25) to the additional books on the second and third shelves.

The number of additional books on the second shelf is 18 more than the number on the first shelf, which means there are 25 + 18 = 43 books on the second shelf.

The number of additional books on the third shelf is 185 more than the number on the first shelf, which means there are 25 + 185 = 210 books on the third shelf.

To find the total number of books, we add the number of books on each shelf: 25 + 43 + 210 = 278.

Therefore, there are 278 books in total on the shelf.
