Question

765 - 45321 • 387 + 653488÷4770 – 659 684÷2​

Answer 1

Пошаговое объяснение:

$765 - 45 = 720 \\ 321 \times 3 = 963 \\ 87 + 653 = 740 \\ 488 \div 4 = 122 \\ 770 - 659 = 111 \\ 684 \div 2 = 342$

Answer 2

To solve this mathematical expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right). Here's the step-by-step solution:

1. Start with the multiplication and division from left to right:

   • 45321 • 387 = 17,547,927
   • 653488 ÷ 4770 = 137

2. Now, your expression becomes: 765 - 17,547,927 + 137 - 659,684 ÷ 2

3. Continue with the addition and subtraction from left to right:

   • 765 - 17,547,927 = -17,547,162
   • -17,547,162 + 137 = -17,547,025
   • -17,547,025 - 659,684 ÷ 2 = -17,547,025 - 329,842 = -17,876,867

So, the result of the expression is -17,876,867.
