Question

if someone could explain how to evaluate absolute value to me I would appreciate it and maybe you could explain how to solve these

Answer 1

absolute value is the non-negative value of a number.

12. | 7 + -33 | + | 4 + 16|
| -26 | + | 20 |

this is the part where you apply the absolute value rule. which turns the |-26| into 26 and the 20 will stay positive.

26 + 20 = 46

Answer 2

When calculating absolute value (like those questions above) you do whatever is in the absolute value bars first (if its just a number then.... just make the number positive, even if it is negative or already positive) and whatever answer you get inside those absolute value bars will ALWAYS be positive unless it's like -[4} then it's a negative number bcz the positive outcome that comes out of the absolute value bars gets multiplied by -1 (or just turned negative). So, for the first one you do 22+48=70 and -7--20=13 and then make the outcome of both of those positive and then subtract them from each other 70-13=57. For the second one you do 7+-33=-26 and 4+16=20 and make the outcome of both of those positive and then you add 26+20=46 and so and so on for the other problems.
