Step-by-step solution

To solve this problem, we will use vertical addition, adding each column digit separately starting from the rightmost column forming the following arrangement:

  • Align the numbers:
       916
      + 95
      ----
       
  • Start with the rightmost column (units):
    • The units digit of 916 916 is 6 6 , and the units digit of 95 95 is 5 5 .
    • Adding these gives 6+5=11 6 + 5 = 11 .
    • Place the 1 1 in the units column and carry over the 1 1 to the tens column.
  • Move to the tens column:
    • The tens digit of 916 916 is 1 1 , and the tens digit of 95 95 is 9 9 . Add these together with the carried over 1 1 : 1+9+1=11 1 + 9 + 1 = 11 .
    • Place the 1 1 in the tens column and carry over the 1 1 to the hundreds column.
  • Finally, address the hundreds column:
    • The hundreds digit of 916 916 is 9 9 , and there is no hundreds digit in 95 95 , so it is 0 0 . Add these along with any carried over number: 9+0+1=10 9 + 0 + 1 = 10 .
    • Place the 0 0 in the hundreds column, and 1 1 will become the new thousands digit.
  • The final sum is then:
       1011
       

Therefore, the solution to the addition problem is 1011\mathbf{1011}.

Final Answer

1011

Key Points to Remember

Essential concepts to master this topic
  • Alignment: Stack numbers right-to-left, matching place value columns perfectly
  • Technique: Add units first: 6 + 5 = 11, write 1 carry 1
  • Check: Verify each column carries correctly: 916 + 95 = 1011 ✓

Common Mistakes

Avoid these frequent errors
  • Forgetting to carry over when column sum exceeds 9
    Don't write double-digit sums like 11 directly in one column = wrong answer like 1916! This ignores place value rules completely. Always write the ones digit and carry the tens digit to the next column.

FAQ

Everything you need to know about this question

What does 'carry over' actually mean?

+

When adding a column gives you 10 or more, you write down the ones digit and 'carry' the tens digit to the next column left. Think of it like exchanging 10 ones for 1 ten!

Why do I start from the rightmost column?

+

You start with the units column because any carrying affects the next column to the left. If you started from the left, you'd miss the carried numbers and get the wrong answer!

What if there's no digit in a column for one number?

+

Treat missing digits as zero! In this problem, 95 has no hundreds digit, so we add 9+0+1=10 9 + 0 + 1 = 10 in the hundreds column.

How do I know if I carried correctly?

+

Double-check each step: Units: 6+5=11 (write 1, carry 1). Tens: 1+9+1=11 (write 1, carry 1). Hundreds: 9+0+1=10 (write 0, carry 1). Final answer: 1011!

Can I check my answer without redoing the whole problem?

+

Yes! Use subtraction to verify: 101195=916 1011 - 95 = 916 . If you get back to your original first number, your addition is correct!
