To find the total number of cars sold by the manufacturer in the years 2010 and 2011, we need to add the number of cars sold in each of these two years.
Step-by-Step Solution:
1. Identify the number of cars sold in 2010:
The car manufacturer sold [tex]\( 2,469,860 \)[/tex] cars in 2010.
2. Identify the number of cars sold in 2011:
The car manufacturer sold [tex]\( 3,123,405 \)[/tex] cars in 2011.
3. Add the number of cars sold in 2010 and 2011 together:
[tex]\[
2,469,860 + 3,123,405
\][/tex]
4. Perform the addition:
Let's add these two numbers step by step:
- Start from the rightmost digit and move to the left.
- Units place: [tex]\( 0 + 5 = 5 \)[/tex]
- Tens place: [tex]\( 6 + 0 = 6 \)[/tex]
- Hundreds place: [tex]\( 8 + 4 = 12 \)[/tex] (write down 2 and carry over 1)
- Thousands place: [tex]\( 9 + 3 = 12 \)[/tex] and plus 1 from the carry over gives [tex]\( 12 \)[/tex] (write down 2 and carry over 1)
- Ten thousands place: [tex]\( 6 + 2 = 8 \)[/tex] and plus 1 from the carry over gives [tex]\( 9 \)[/tex]
- Hundred thousands place: [tex]\( 4 + 1 = 5 \)[/tex]
- Millions place: [tex]\( 2 + 3 = 5 \)[/tex]
So, the addition can be written out formally:
[tex]\[
\begin{array}{r}
\ 2469860 \\
+ \ 3123405 \\
\hline
\ 5593265 \\
\end{array}
\][/tex]
Thus, the total number of cars sold by the manufacturer in 2010 and 2011 combined is:
[tex]\[
\boxed{5,593,265}
\][/tex]
