12 ARITHMETIC,
The 5 in the dividend and 5 in the divisor are divisible
by 5, since 5 divided by 5 equals 1. Cross off the 5
of the dividend and write the 1 over it ; also, cross off the 5
of the divisor and write the 1 under it. Thus,
1
4x6x^x2x2 _
1x^x3x1

The 5 in the dividend and 5 in the divisor are not to be
considered any longer, and, in fact, may be erased entirely
and 1 and 1 placed in their stead, and treated as if the 5 and
5 never existed. Thus,
4X 6 X 1 X 2X2 _
1X1X3X1 ~
The 6 in the dividend and 3 in the divisor are divisible by
3, since 6 divided by 3 equals 2, and 3 divided by 3 equals 1.
Cross off the 6 and place 2 oiier it ; also, cross off the 3 and
place 1 under it. Thus,
2
4x 0Xlx2x2 _

The 6 and 3 are not to be considered any longer, and, in
fact, may be erased entirely and 2 and 1 placed
in their
stead, and treated as if the 6 and 3 never existed. Thus,
4x2x1x2x2 32 .
