Question

Вычислите: (80-26):12•15-35•11=?

Answer 1

Распишу всё по действиям, чтобы тебе было понятно. Сначала выполняется действие в скобках, затем деление, далее два умножения и только потом вычитание.

1. 80-26 = 54

2. 54/12 = 4.5

3. 4.5*15 = 67.5

4. 35*11 = 385

5. 67.5 - 385 = -317.5

(80-26)/12*15-35*11 = -317.5

Ответ: -317.5

Answer 2

To calculate the expression (80-26)/1215-3511, follow the order of operations, which is commonly remembered as PEMDAS:

1. Parentheses
2. Exponents
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's solve it step by step:

Step 1: Perform the subtraction inside the parentheses. (80 - 26) = 54

Step 2: Perform the division. 54 / 12 = 4.5

Step 3: Perform the multiplication. 4.5 * 15 = 67.5

Step 4: Perform the multiplication. 35 * 11 = 385

Step 5: Perform the subtraction. 67.5 - 385 = -317.5

Therefore, (80-26)/1215-3511 equals -317.5.
