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

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

00:09 Place the ones digit, and remember 1 above

00:12 Add tens with tens, remember to add 1 to the calculation

00:19 Place in the tens position

00:21 And this is the solution to the question

Step-by-Step Solution

Let's solve the problem of adding 37 and 43 using vertical addition:

Step 1: Align the Numbers Vertically
Write the numbers such that their digits align according to place value: $\begin{array}{c} & 37 \\ + & 43 \\ \hline \end{array}$
Step 2: Add the Units Place
Start with the units place (rightmost digits). Add 7 (from 37) to 3 (from 43): $7 + 3 = 10$
Since 10 is greater than 9, we write 0 in the units place and carry over 1 to the tens place.
Step 3: Add the Tens Place
Now, add the tens digits: 3 (from 37) and 4 (from 43), plus the 1 we carried over: $3 + 4 + 1 = 8$
Step 4: Write the Final Sum
Combining these results, we place 0 in the units position and 8 in the tens position, resulting in: $\begin{array}{c} & 37 \\ + & 43 \\ \hline & 80 \\ \end{array}$

Therefore, the sum of 37 and 43 is $80$ .
