Question

Lets play a number game which involves subtraction:
a) Draw a square of 7cm.
b) Choose any four numbers and write them at the corners of the square.
c) Find the difference between each pair of numbers on each side of the square and write
the difference at the midpoints of each side.
d) Join the midpoints to form a new square. Thus, we get difference obtained in step 3 at
the corners of the new square.
e) Find the difference between each pair of numbers on each side of the new square and
write the difference at the midpoints of each side.
f) Repeat steps 4 and 5 until you obtain 0 on all corners of the square
