Solve Vertical Addition: Adding 100 + 5 Step by Step

$\begin{aligned} &100 \\ +& \\ &~~~~5 \\ &\underline{\phantom{776}} & \\ \end{aligned}$

To solve this problem, we will use vertical addition.

Let's perform the steps:

• Step 1: Write the numbers 100 and 5 vertically, aligning them by place value. Since 5 is a single-digit number, it will align under the ones place of 100. This gives us:

  $\begin{aligned} &100 \\ +& \\ &~~5 \\ \end{aligned}$

• Step 2: Add the numbers column by column, starting from the right.

  • Add the ones place: $0 + 5 = 5$
  • Add the tens place: $0 + 0 = 0$
  • Add the hundreds place: $1 + 0 = 1$

  This results in a sum of $105$.

Therefore, the solution to the problem is $105$.
