First, let's solve the expression inside the parentheses:
87 x 78 = 6786
412,300 ÷ 70 = 5890
Now, let's solve the outer expression:
(6786 - 5890) x 970 = 896 x 970 = 869120
Finally, let's multiply the result by 1000:
10,000 x 1000 = 10,000,000
Now, subtract 1,818,880:
10,000,000 - 1,818,880 = 8,181,120
So, the final answer is 8,181,120.
