In your question, we are multiplying 6 negative integers. 6 is an even number so their product is positive. 12 positive integers will also give a positive integer. So product of 6 negative and 12 positive integers is positive.

Therefore, the number must be taken away from the sum of 6789678 and 1234567 to make it equal to the difference of the given numbers is 2469134.

Answer: The product of six negative and twelve positive integer is 2 negative integer. Therefore, (- 6)×(-2) = +12
