To solve this problem of adding the numbers and using vertical addition, we will proceed as follows:
First, write the numbers vertically, ensuring their digits are aligned as follows:
32 + 89 ------
Now, let's add the numbers column by column:
Therefore, lining it up nicely, the sum can be calculated as:
32 + 89 ------ 121
Thus, the result of adding and is .
The correct choice is Choice 1: .
121
\( \begin{aligned} &90 \\ +& \\ &~~9\\ &\underline{\phantom{776}} & \\ \end{aligned} \)
Carrying means when a column adds up to 10 or more, you write down the units digit and move the tens digit to the next column. For example, when 2 + 9 = 11, write 1 and carry 1.
Each column can only hold one digit! Writing 11 would mean you have two digits in one place value position, which breaks our number system rules.
Write the carried number small and above the next column as a reminder. Then add all three numbers: the two original digits plus the carried digit.
Always double-check your work! Add the numbers horizontally (32 + 89) to verify your vertical addition result matches.
Yes! When any column sum equals 10, write 0 in that column and carry 1 to the next column, just like with sums greater than 10.
