Question

-3,2+6,3 19+|-11| 3 и -9 +-11 |8|+|-12|

Answer 1

$- 3.2 + 6.3 = 3.1$

$19 + | - 11| = 30$

$3 \times ( - 9) + ( - 11) = - 38$

$|8| + | - 12| = 20$

Answer 2

Let's solve each expression step by step:

1. $-3.2 + 6.3$:

   $$-3.2 + 6.3 = 3.1$$

2. $19 + |-11|$: The absolute value of -11 is 11, so:

   $$19 + 11 = 30$$

3. $-9 + -11$:

   $$-9 + -11 = -20$$

4. $|8| + |-12|$: The absolute values of 8 and -12 are 8 and 12, respectively:

   $$|8| + |-12| = 8 + 12 = 20$$

So, the final expressions are: $3.1, \ 30, \ -20, \ 20$
