a+ax2+[a+ax(2:2)] =
a + 2a +[ a + a x 1] =
a + 2a + [ a + a] =
a + 2a + 2a =
5a
a + 2a +[ a + a x 1] =
a + 2a + [ a + a] =
a + 2a + 2a =
5a
a + a x 2 + [ a + a x ( 2 : 2 ) ] =
= a + 2a + [ a + a x 1 ]
= a + 2a + [ a + a ]
= a + 2a + 2a
= 3a + 2a
= 5a
= a + 2a + [ a + a x 1 ]
= a + 2a + [ a + a ]
= a + 2a + 2a
= 3a + 2a
= 5a
