Question
Multiplication of ̶ 2, ̶ 7 and ̶ 10 gives
- -34
- 19
- -140
- 90
Hint:
Product of odd number of negative integers are always negative.
The correct answer is: -140
We are asked to find the product of -2, -7 and -10. That is, -2*-7*-10. Apply the BODMAS rule, we have to perform the multiplication from the left. Thus, we get:
-2*-7*-10=(-2*-7)*-10
=14*-10
=-140.
Hence, the correct answer is option c.
