=1+1/32-1/32-(1/2+1/4+1//+1/16+1/32)
=1+1/32--(1/2+1/4+1/8+1/16+1/32+1/32)
=1+1/32--(1/2+1/4+1/8+1/16+1/16)
=1+1/32--(1/2+1/4+1/8+1/8)
=1+1/32-(1/2+1/2)
=1+1/32-1
=1/32
=1-(1/2+1/4+1//+1/16+1/32)
=1+1/32-1/32-(1/2+1/4+1//+1/16+1/32)
=1+1/32--(1/2+1/4+1/8+1/16+1/32+1/32)
=1+1/32--(1/2+1/4+1/8+1/16+1/16)
=1+1/32--(1/2+1/4+1/8+1/8)
=1+1/32-(1/2+1/2)
