Question

12+6:2-7*2 порядок действия решения примера

Answer 1

1)6:2=3
2)7×2=14
3)12+3=15
4)15-14=1

Answer 2

По моему, сначала деление и умножение, а потом + с -.

А именно:

6:2 = 3

7*2=14

12+3=15

15 - 1 4 = 1

Answer 3

To solve the expression "12 + 6 ÷ 2 - 7 × 2," you need to follow the order of operations (also known as BIDMAS or PEMDAS). The order of operations is as follows:

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

Let's apply these rules to the expression:

1. Start with Division and Multiplication: 6 ÷ 2 = 3 7 × 2 = 14

Now the expression becomes: "12 + 3 - 14."

2. Next, perform Addition and Subtraction from left to right: 12 + 3 = 15 15 - 14 = 1

So, the result of the expression "12 + 6 ÷ 2 - 7 × 2" is 1.
