Problem |
Simplify: \$| - 19 | + | 61 | + | - 32 | \$. |
|
2 |
Step |
Let’s start by evaluating the absolute values: \$| - 19 | + | 61 | + | - 32 | \$ |
|
3 |
Step |
The absolute value of any negative number is its positive counterpart. \$|-19|\$ = 19 |
|
4 |
Step |
61 is already positive so, the absolute value is \$|61|\$ = 61 |
|
5 |
Step |
The absolute value of any negative number is its positive counterpart. \$|-32|\$ = 32 |
|
6 |
Step |
Now, we substitute these values back into the expression: \$| - 19 | + | 61 | + | - 32 | \$ 19 + 61 + 32 |
|
7 |
Step |
Adding these numbers together: 19 + 61 + 32 = 112 |
|
8 |
Solution |
So, the simplified expression is 112. |

10 |
Choice-A |
This option is correct. After computing the absolute values and summing them, we get a total of 112 |
Correct 112 |
11 |
Choice-B |
This option is incorrect because it represents a negative value. However, the sum of absolute values cannot be negative, so -131 is not possible |
Wrong -131 |
12 |
Choice-C |
This option is incorrect. The sum of the absolute values of -19, 61, and -32 is greater than 10 |
Wrong 10 |
13 |
Choice-D |
This option is incorrect because it represents a negative value. However, the sum of absolute values cannot be negative, so -71 is not possible |
Wrong -71 |
