3.2x0.64+3.2x0.34
=3.2x(0.64+0.34)
=3.2x1
=3.2
3.23x0.64+3.23x0.34
=3.23x(0.64+0.34)
=3.23x1
=3.23
=3.2x(0.64+0.34)
=3.2x1
=3.2
3.23x0.64+3.23x0.34
=3.23x(0.64+0.34)
=3.23x1
=3.23

3.23X0.64+3.2X0.34
=3.23X2X0.32+3.2X0.34
=3.2X(0.323X2+0.34)
=3.2X(0.646+0.34)
=3.2X0.986
=3.2X1-3.2X0.01-3.2X0.004
=3.2-0.032-0.0128
=3.2-0.0448
=3.1552
=3.23X2X0.32+3.2X0.34
=3.2X(0.323X2+0.34)
=3.2X(0.646+0.34)
=3.2X0.986
=3.2X1-3.2X0.01-3.2X0.004
=3.2-0.032-0.0128
=3.2-0.0448
=3.1552
