Problem |
Evaluate the expression: |
|
2 |
Step |
To evaluate the expression: { [ 3 + \$ | - ( 5 − 2 )| \$ ] × 2 } − 4 |
|
3 |
Step |
Inside the innermost parentheses, we have \$ | - ( 5 − 2 )| = | - 3 | \$ |
|
4 |
Step |
The absolute value of - 3 is 3, we have: \$ | - 3 | = 3\$ |
|
5 |
Step |
Then we add 3 to 3, which equals 3 + 3 = 6 |
|
6 |
Step |
After that, we multiply 6 by 2, which equals \$ 6 times 2 = 12 \$ |
|
7 |
Step |
Finally, we subtract 4 from 12, which equals 12 - 4 = 8 |
|
8 |
