Answer :

To solve the problem of adding 17 to 139, we can perform simple arithmetic addition.

Here's how we can do it step-by-step:

  1. Align the Numbers: Position the numbers so that their units digits are in the same column. It would look like this:

    [tex]\begin{array}{c} \phantom{0}139 \\ +017 \\ \hline \end{array}[/tex]

  2. Add the Units Column: Start by adding the digits in the units column (rightmost). In this case, you add 9 and 7:

    [tex]9 + 7 = 16[/tex]

    Write down 6 and carry over 1 to the tens column.

  3. Add the Tens Column: Now, add the digits in the tens column, including the carryover. This means adding 3, 1 (the carryover), and 1:

    [tex]3 + 1 + 1 = 5[/tex]

    Write down 5.

  4. Add the Hundreds Column: Finally, add the digits in the hundreds column:

    [tex]1 + 0 = 1[/tex]

  5. Combine the Results: The full sum is then:

    [tex]139 + 17 = 156[/tex]

So, 17 added to 139 gives a total of 156.
