Answer : 630

Step by step explanation :

 - 7 \times ( - 5) \times ( - 9) \times ( - 2)

Use the Rules of Signs. Multiplying an even number of negative factors equals a positive.

 =  > 7 \times 5 \times 9 \times 2

To make the calculation easier, first multiply the numbers that result in multiples of 10.

 =  > 7 \times 10 \times 9

Multiply the numbers.

 =  > 70 \times 9

Multiply the numbers.

 =  > 630
