Answer 1

| 1,9 | + | -11 | =|-9.1|
| -20 | - | -12,4| =|-7.6|
|0,7|×|-0,8|=|-0.56|
|-4,16|:|8|=|-0.52|

Answer 2

To calculate the expressions you provided, let's go through them step by step:

1. |1,9|: The vertical bars surrounding the number 1.9 indicate the absolute value. The absolute value of a number is its distance from zero on the number line, always resulting in a positive value. In this case, the absolute value of 1.9 is 1.9.

2. -11: This is a simple negative number. The value of -11 remains the same.

3. +: The plus sign indicates addition between two numbers.

4. -20: This is another negative number. The value of -20 remains the same.

5. +: Addition.

6. -12.4: This is a negative number. The value of -12.4 remains the same.

7. +: Addition.

8. 0.7: This is a positive number. The value of 0.7 remains the same.

9. ×: The multiplication symbol.

10. -0.8: This is a negative number. The value of -0.8 remains the same.

11. =: The equal sign indicates that we need to find the value of the expression.

To calculate the expression, let's follow the order of operations (PEMDAS/BODMAS):

1. |1.9| = 1.9 2. -11 + -20 = -31 3. -31 + -12.4 = -43.4 4. -43.4 + 0.7 = -42.7 5. -42.7 × -0.8 = 34.16 6. -4.16 ÷ 8 = -0.52

Therefore, the answer to the expression is -0.52.
