To solve this problem, we will use vertical addition, adding each column digit separately starting from the rightmost column forming the following arrangement:
916 + 95 ----
1011
Therefore, the solution to the addition problem is .
1011
\( \begin{aligned} &12 \\ +& \\ &~~2 \\ &\underline{\phantom{776}} & \\ \end{aligned} \)
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!
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!
Treat missing digits as zero! In this problem, 95 has no hundreds digit, so we add in the hundreds column.
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!
Yes! Use subtraction to verify: . If you get back to your original first number, your addition is correct!
