Hey there!

In today's technology, new computers (especially laptops) are coming out all the time. Laptops are also not considered something to have the longevity of a desktop computer and are not nearly as easy to fix on your own, especially newer models that require lots of patience, skill, and special tools. At this point, it's important to ask yourself whether or not spending money on an old machine to get it repaired is worth it, especially considering how much faster a new computer for the same price as repairs would be. 

Hope this helped you out! :-)

Write an application that displays every perfect number from 1 through 1,000. A perfect number is one that equals the sum of all
matrenka [14]

Answer:

Written in Python

for num in range(1,1001):

    sum=0

    for j in range(1,num+1):

         if num%j==0:

              sum = sum + j

                   if num == sum:

                        print(str(num)+" is a perfect number")

Explanation:

This line gets the range from 1 to 1000

for num in range(1,1001):

This line initializes sum to 0 for each number 1 to 1000

    sum=0

This line gets the divisor for each number 1 to 1000

    for j in range(1,num+1):

This following if condition line checks for divisor of each number

<em>          if num%j==0: </em>

<em>               sum = sum + j </em>

The following if condition checks for perfect number

                   if num == sum:

                        print(str(num)+" is a perfect number")
