Consider two integers, $x$ and $y$. The integer $x$ is defined as the sum of the first 100 positive integers, while the integer $y$ is defined as the product of the first 10 positive integers. Calculate the values of $x$ and $y$:
$x = 1 + 2 + 3 + ... + 100$
$y = 1 \times 2 \times 3 \times ... \times 10$
Determine the relationship between Quantity A ($x$) and Quantity B ($y$).
