Question

$0.4+0.4=$

00:00 Solve

00:04 We will use long addition for calculation

00:08 We will place the decimal point in the appropriate position

00:11 We will start by adding the smallest matching digits

00:16 We will place and continue to add and calculate

00:20 And this is the solution to the question

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

Step 1: Align the decimal points vertically in the numbers to be added.
Step 2: Add the numbers as if they were whole numbers, placing the decimal correctly in the sum.

Let's perform the addition:

Step 1: Align the numbers $0.4$ and $0.4$ : $\begin{array}{c} \phantom{+}0.4 \\ + 0.4 \\ \hline \end{array}$

Step 2: Add $4$ and $4$ in the tenths place, which gives us $8$ . The decimal point remains in the same position, resulting in $0.8$ .

Therefore, the sum of $0.4 + 0.4$ is $0.8$ .

0.8
