Step-by-step explanation:
3 is being multiplied by the numbers in the bracket so
18-(3x1+3x5)
18-(3+15)
18-(18)
answer is 0
1,000,000,000,000 should be the correct answer. Because there are only 1's and 0's you can just multiply 1 x 1 and then add up all of the zeros in the equation (6+6 in this case) and add them behind the product.
The answer is c. because it is.
