Question

$2.5+\text{3}.1=$

00:00 Solve

00:03 We will use long addition for calculation

00:09 We will place the decimal point in the appropriate position

00:12 We will start by adding the smallest corresponding digits

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

00:19 And this is the solution to the question

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

Step 1: Align the numbers 2.5 and 3.1 by their decimal points.
Step 2: Add the digits in each column starting from the rightmost digit (the tenths column in this case).

Now, let's work through each step:

Step 1: Align the numbers by decimal points:

$\phantom{00}2.5$
$+3.1$

Step 2: Perform the addition:
- Add the tenths column: $5 + 1 = 6$
- Add the units column: $2 + 3 = 5$

Therefore, by aligning and adding the numbers correctly, the solution to the problem is $5.6$ .
