  1. ☐ Perfect Integers @created(18-01-31 18:21) @due(18-02-01 18:32)
  2.         a positive integer (n > 0) that is equal to the sum of it's proper divisors
  3.         divisors of 6 /= 1,2,3
  4.         6 is Perfect Int because 1 + 2 + 3 == 6
  5.  
  6.         1.) gather the user #
  7.         2.) Check whether # is perfect integer or not
  8.           a.) If so, tell that it is. Probably show the integers used to determine that it is a perfect integer
  9.           b.) If not, tell that it is not. Probably show the integers used to determine that it is not a perfect integer
  10.  
  11.         How to decide that it is a perf. integer
  12.           while i is less than n (this will run until i >= n is true)
  13.             if n modulo i equals 0 then
  14.               sum += i
  15.             else
  16.               discard
  17.           if sum is equal to n
  18.             n is perfect number
  19.           else
  20.             n is not perfect number
  21.       ☐ Find Slope + Intercept of line when given two points @created(18-01-31 18:21) @due(18-02-01 18:32)
  22.         Pretty simple
  23.         1.) gather the user's two points (±x1,±y1) -- (±x2,±y2)
  24.         2.) equation for slope is (y2 - y1)/(x2-x1)
  25.         3.) finding the y intercept (the 'b' in y=mx+b) is simple
  26.           a.) the slope is m in y=mx+b
  27.           b.) solve for b, so b = -(mx) + y
  28.           c.) for x,y take xn, yn where n is one of the two points
  29.           d.) solve for b
  30.  
  31.         EXAMPLE (Done in SpeedCrunch)
  32.           x1
  33.           = 23
  34.  
  35.           y1
  36.           = −7
  37.  
  38.           x2
  39.           = 2
  40.  
  41.           y2
  42.           = 9
  43.  
  44.           m = (y2−y1)/(x2−x1)
  45.           = −0.76190476190476190476
  46.  
  47.           b = −(m×x1) + y1
  48.           = 10.52380952380952380952
  49.  
  50.           b = −(m×x2) + y2
  51.           = 10.52380952380952380952
