SHORTCUTS

Each program trick contains a section describing the shortcut method.
The steps are numbered and are correlated to the numbered steps in the EXAMPLE section.

Notice that the sample problem on the HOME page is a sum of two squares.
However, the two numbers are special:
     a) the outer numbers total 10   (i.e.  1 + 9 = 10) &
     b) the inner numbers differ by 1 (i.e. 4 = 3 + 1)
This trick will only work on summing the squares of two numbers with the two properties above.

          2             2
     AB     +   CD     =  ??       (where A + D  = 10 and  B  = C + 1)

   1)  Square A        2)   Square B      3) Sum the squares    4) Multiply by 101
