Vertical Addition: Double digit addition within 100

To solve this problem, we'll follow a step-by-step vertical addition method:

• Step 1: Arrange the numbers vertically: $\begin{aligned} &12 \\ + & \\ &88 \\ \end{aligned}$ Make sure the digits of the numbers are aligned correctly: units under units and tens under tens.
• Step 2: Start by adding the numbers in the units place (rightmost column): $2 + 8 = 10$

Since $10$ is a two-digit number, write down $0$ in the units place under this column and carry over $1$ to the tens column (left). Carrying over is essential when the sum of any column exceeds 9.

• Step 3: Next, add the numbers in the tens place, don't forget adding the carry from the previous addition: $1 + 1 + 8 = 10$

As before, $10$ is a two-digit number. Write down $0$ in the tens place and carry over $1$ (although in this case, it gets added to a zero since this is the leftmost column, resulting in a new column).

Thus, the complete addition looks like this: $\begin{aligned} &12 \\ + & \\ &88 \\ & \underline{100} \end{aligned}$

Therefore, the correct solution to the problem is $100$, which corresponds to the answer choice provided.

To solve this problem, we'll use vertical addition as follows:

Step 1: Arrange the numbers vertically with the place values aligned.

  $26$
+ $74$
$\underline{\phantom{776}}$

Step 2: Add the numbers starting from the ones column:
- Add the ones place: $6 + 4 = 10$. Write down $0$ and carry over $1$ to the tens column.

  $26$
+ $74$
$\underline{\phantom{776}}$
  $00$

Step 3: Move to the tens column: Add $2 + 7 = 9$, then add the carried over $1$ to get $10$.
- Write down $10$.

     $26$
  + $74$
  $\underline{\phantom{6707}}$
  $100$

Therefore, the sum of $26$ and $74$ is $100$.

The correct answer amongst the choices provided is :

100

.

Therefore, the solution to the problem is $100$.

To solve this problem, we'll follow these steps:

• Step 1: Align the numbers vertically by their place value.
• Step 2: Add the digits in the units column.
• Step 3: Manage any carryover if necessary.
• Step 4: Add the digits in the tens column along with any carryover.

Now, let's work through each step:

Step 1: Align the numbers.

48
+52
___

Step 2: Add the digits in the units column:
8 (from 48) + 2 (from 52) = 10.
This gives us 0 in the units place and we carry over 1 to the tens place.

Step 3: Add the digits in the tens column, including the carried over 1:

4 (from 48) + 5 (from 52) + 1 (carryover) = 10.

Thus, the digit 0 goes to the tens place, and 1 will be placed in the hundreds place.

Therefore, the full solution looks like this:

48
+52
___
100

Therefore, the solution to the problem is $100$.

To solve this problem using vertical addition, follow these steps:

• Step 1: Write the numbers vertically, ensuring the digits are aligned by place value:

$\begin{array}{c} 56 \\ + 44 \\ \underline{\phantom{776}} \\ \end{array}$

• Step 2: Add the units digits (rightmost column). The units digit of 56 is 6, and for 44, it is 4.

Sum: $6 + 4 = 10$.

• Step 3: Write down the 0 from the sum (10) in the units place and carry over the 1 to the tens place.
• Step 4: Add the tens digits (next column to the left). The tens digit of 56 is 5, and for 44, it is 4. Add these along with the carried-over 1.

Sum: $5 + 4 + 1 = 10$.

• Step 5: Write down the full result (100) below the line.

Therefore, the sum of 56 and 44 is $\textbf{100}$.

This corresponds to answer choice 1.
