10000×1000-1818880÷(87×78-412300÷70)×970

To solve this expression, we need to follow the order of operations:

Step 1: Calculate the innermost parentheses. (87 × 78) = 6786 (412300 ÷ 70) = 5890

Step 2: Perform the division inside the parentheses. (6786 - 5890) = 896

Step 3: Continue evaluating the expression after removing parentheses. 10000 × 1000 - 1818880 ÷ 896 × 970

Step 4: Perform the division and multiplication from left to right. 10000 × 1000 = 10,000,000 1818880 ÷ 896 = 2030 2030 × 970 = 1,971,100

Step 5: Subtract the result of the multiplication from the result of the division. 10,000,000 - 1,971,100 = 8,028,900

Therefore, the final result is 8,028,900.
