problem

Find the number of positive integers less than 1000000 which are less than or equal to the sum of their proper divisors. If your answer is XX and the actual value is YY, your score will be max(0,20−80|1−XY|)\max \left(0,20-80\left|1-\frac{X}{Y}\right|\right) rounded to the nearest integer.
Plain-text mathematical notation (without MathML)
Find the number of positive integers less than 1000000 which are less than or equal to the sum of their proper divisors. If your answer is X and the actual value is Y, your score will be max(0,20−80|1−(X)/(Y)|) rounded to the nearest integer.
Original LaTeX notation
Find the number of positive integers less than 1000000 which are less than or equal to the sum of their proper divisors. If your answer is $X$ and the actual value is $Y$, your score will be $\max \left(0,20-80\left|1-\frac{X}{Y}\right|\right)$ rounded to the nearest integer.
