Step 1.1

Rewrite using the commutative property of multiplication.

$2 \cdot 4 m b - 3 a \cdot (2 n) - 0.2 b \cdot (5 m) + n \cdot (5 a) - 5 b m + 8 n a$

Step 1.2

Multiply $2$ by $4$ .

$8 m b - 3 a \cdot (2 n) - 0.2 b \cdot (5 m) + n \cdot (5 a) - 5 b m + 8 n a$

Step 1.3

Rewrite using the commutative property of multiplication.

$8 m b - 3 \cdot 2 a n - 0.2 b \cdot (5 m) + n \cdot (5 a) - 5 b m + 8 n a$

Step 1.4

Multiply $- 3$ by $2$ .

$8 m b - 6 a n - 0.2 b \cdot (5 m) + n \cdot (5 a) - 5 b m + 8 n a$

Step 1.5

Rewrite using the commutative property of multiplication.

$8 m b - 6 a n - 0.2 \cdot 5 b m + n \cdot (5 a) - 5 b m + 8 n a$

Step 1.6

Multiply $- 0.2$ by $5$ .

$8 m b - 6 a n - b m + n \cdot (5 a) - 5 b m + 8 n a$

Step 1.7

Rewrite using the commutative property of multiplication.

$8 m b - 6 a n - b m + 5 n a - 5 b m + 8 n a$
