Answer 2

1) To solve the expression |-154|-|-63|+|19|, we need to follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

First, let's simplify the expression |-154|. The absolute value of -154 is 154.

Next, let's simplify the expression |-63|. The absolute value of -63 is 63.

Now, we have the expression 154 - 63 + 19. Performing the subtraction and addition, we get the final result of 110.

2) To solve the expression |-7,8|+|-3,6|-|+1,1|, we follow the same order of operations.

First, let's simplify the expression |-7,8|. The absolute value of -7.8 is 7.8.

Next, let's simplify the expression |-3,6|. The absolute value of -3.6 is 3.6.

Now, we have the expression 7.8 + 3.6 - 1.1. Performing the addition and subtraction, we get the final result of 10.3.

3) To solve the expression |-7,8|:|-1,3|*|-2,4|, we again follow the order of operations.

First, let's simplify the expression |-7,8|. The absolute value of -7.8 is 7.8.

Next, let's simplify the expression |-1,3|. The absolute value of -1.3 is 1.3.

Now, let's simplify the expression |-2,4|. The absolute value of -2.4 is 2.4.

Now, we have the expression 7.8 : 1.3 * 2.4. Performing the division and multiplication, we get the final result of 15.2.

4) To solve the expression |+4+1/6|*|-2+2/5|:|-3|, we follow the order of operations.

First, let's simplify the expression |+4+1/6|. The absolute value of +4+1/6 is 4+1/6.

Next, let's simplify the expression |-2+2/5|. The absolute value of -2+2/5 is 2-2/5.

Now, let's simplify the expression |-3|. The absolute value of -3 is 3.

Now, we have the expression (4+1/6) * (2-2/5) : 3. Performing the addition, subtraction, multiplication, and division, we get the final result of 2 1/2 or 2.5.

I hope this helps! Let me know if you have any further questions.
