Problem |
Simplify : \$| 17 times 5 | \div | 4 - 19 | \$. |
|
2 |
Step |
Given the expression |
\$| 17 times 5 | \div | 4 - 19 | \$ |
3 |
Hint |
First calculate the values inside the absolute values: |
|
4 |
Step |
The absolute value of any positive number is the number itself. |
\$|17 * 5|\$ = \$|85|\$ = 85 |
5 |
Step |
The absolute value of any negative number is its positive counterpart. |
\$|4-19|\$ = \$|-15|\$ = 15 |
6 |
Step |
Now, we substitute these values back into the original expression: |
\$85/15\$ ⇒ \$ 17/3\$ |
7 |
Solution |
The simplified expression is \$ 17/3\$. |
