4.8 {1.6 +1.2 x 0.25 -(0.2+ (1-0.8)}

First Need to solve  {1.6 +1.2 x 0.25 -(0.2+ (1-0.8)}

Solving (1-0.8) first

=  4.8 {1.6 +1.2 x 0.25 -(0.2+ ( 0.2)}

=  4.8 {1.6 +1.2 x 0.25 -(0.2+   0.2)}

Solving (0.2+   0.2)

=  4.8 {1.6 +1.2 x 0.25 -(0.4)}

=  4.8 {1.6 +1.2 x 0.25 - 0.4}

Solving 1.2 x 0.25

=  4.8 {1.6 + 0.3 - 0.4}

Performing Addition

=  4.8 {1.9 - 0.4}

Performing Subtraction

=  4.8 {1.5}

= 4.8 * 1.5

= 7.2

4.8 {1.6 +1.2 x 0.25 -(0.2+ (1-0.8)} = 7.2
