Solve Vertical Addition: Adding 100 + 5 Step by Step

Question

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

00:00 Solve

00:03 Each time we'll calculate the sum of 2 digits, and then substitute

00:06 Let's start by adding ones with ones

00:09 Put 0 in the missing digits

00:12 Add the tens, and substitute in tens place

00:15 Put 0 in the missing digits

00:19 Add the hundreds, and substitute in hundreds place

00:22 And this is the solution to the question

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 $105$ .
