tính bằng cách thuận tiện Sure, I can help with that. Could you please provide the math problem in text format or describe it to me? a 56 x 89 - 46 x 89 Để giải bài toán này, ta có thể sử dụng tính chất phân phối của phép nhân đối với phép trừ. Ta có thể viết lại bài toán như sau: $$ $$ $$ Vậy kết quả cuối cùng là 890. B 700 + 197 - 200 + 203 To solve the given math problem, we can follow the order of operations (PEMDAS/BODMAS) which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). First, we perform the operations inside the parentheses: $$ Next, we add and subtract from left to right: $$ Then, $$ Finally, $$ Therefore, the final answer is not equal to the given answer of 1712. If you would like me to help you reach the final answer of 1712 using a different approach or if there was a mistake in providing the problem or final answer, please let me know.
