Question

1+4+0×97+56-90+643543×3457÷123​

Answer 1

Пошаговое объяснение:

1. Сначала идет умножение и деление

1) 0*97 = 0

2) 643543*3457 = 2224728151

3) 2224728151/123 = 18087220,7398

2. Дальше сложение и вычитание

1) 1+4 = 5

2) 56-90 = -34

Итого мы получаем:

5-34+18087220,7398 = 18087191,7398

Ответ: 18087191,7398

Answer 2

To calculate the expression:

1 + 4 + 0 × 97 + 56 - 90 + 643543 × 3457 ÷ 123

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).

In your expression, there are no parentheses or exponents, so you perform multiplication and division from left to right first, then addition and subtraction from left to right:

1 + 4 + 0 × 97 + 56 - 90 + 643543 × 3457 ÷ 123

= 1 + 4 + 0 + 56 - 90 + (643543 × 3457 ÷ 123)

Now, calculate the multiplication and division inside the parentheses:

643543 × 3457 = 2227098851 2227098851 ÷ 123 ≈ 18122292.51 (rounded to two decimal places)

Now, substitute this result back into the expression:

1 + 4 + 0 + 56 - 90 + 18122292.51

Now, perform the addition and subtraction from left to right:

1 + 4 = 5 5 + 0 = 5 5 + 56 = 61 61 - 90 = -29 -29 + 18122292.51 ≈ 18122263.51 (rounded to two decimal places)

So, the final result is approximately 18122263.51.
