$300 \cdot 5.1 \cdot (- 98 - - 65)$

Step 1

Replace all occurrences of $-$ $-$ with a single $+$ . Two consecutive minus signs have the same mathematical meaning as a single plus sign because $- 1 \cdot - 1 = 1$

$300 \cdot 5.1 \cdot (- 98 + 65)$

Step 2

Multiply $300$ by $5.1$ .

$1530 \cdot (- 98 + 65)$

Step 3

Add $- 98$ and $65$ .

$1530 \cdot - 33$

Step 4

Multiply $1530$ by $- 33$ .

$- 50490$
