Question

- 36 + 60 : 4 : 2 + 34 42 + 54 : 3 : 2 - 18(760 + 100) - (430 + 230)(970 — 340) + (250 + 120)по действиям​

Answer 1

- 36 + 60 : 4 : 2 + 34 = 5,5

1) 60 : 4 = 15

2) 15 : 2 = 7,5

3) -36 + 7,5 = -28,5

4) -28,5 + 34 = 5,5

Ответ: 5,5.

42 + 54 : 3 : 2 - 18 = 33

1) 54 : 3 = 18

2) 18 : 2 = 9

3) 42 + 9 = 51

4) 51 - 18 = 33

Ответ: 33.

(760 + 100) - (430 + 230) = 200

1) 760 + 100 = 860

2) 430 + 230 = 660

3) 860 - 660 = 200

Ответ: 200.

(970 - 340) + (250 + 120) = 260

1) 970 - 340 = 630

2) 250 + 120 = 370

3) 630 - 370 = 260

Ответ: 260.

Answer 2

It seems like you've provided a series of mathematical expressions to evaluate. Let's break down each expression step by step:

1. $36 + \frac{60}{4} \times 2 + 34$: First, perform the division within the parentheses: $60 \div 4 = 15$. Then, perform the multiplication: $15 \times 2 = 30$. Finally, add up all the values: $36 + 30 + 34 = 100$.

2. $42 + \frac{54}{3} \times 2 - 18(760 + 100)$: First, perform the division within the parentheses: $54 \div 3 = 18$. Then, perform the multiplication: $18 \times 2 = 36$. Next, calculate the value within the second parentheses: $760 + 100 = 860$. Then, perform the multiplication: $18 \times 860 = 15480$. Finally, subtract: $42 + 36 - 15480 = -15402$.

3. $(430 + 230)(970 - 340) + (250 + 120)$: First, calculate the values within the parentheses: $430 + 230 = 660$ and $970 - 340 = 630$. Then, perform the multiplication: $660 \times 630 = 415800$. Next, calculate the sum within the second parentheses: $250 + 120 = 370$. Finally, add the results: $415800 + 370 = 416170$.

4. $-18(760 + 100)$: Calculate the value within the parentheses: $760 + 100 = 860$. Then, perform the multiplication: $-18 \times 860 = -15480$.

Now, let's add up the results of all the expressions: $100 + (-15402) + 416170 - 15480 = 405288.$

So, the final result of evaluating all the expressions is 405288.
