Please only post your questions once. Repeating posts will not get a quicker response. In addition, it wastes our time looking over reposts that have already been answered in another post. See your previous post. Thank you.
192 + 47 =
256 +1,273
To add the numbers vertically, follow these steps:
Step 1: Align the numbers vertically, with the units, tens, hundreds, and thousands in their respective columns.
```
2 5 6
+ 1 2 7 3
______________
```
Step 2: Start from the rightmost column (units column) and add the digits in that column. In this case, 6 + 3 equals 9.
```
2 5 6
+ 1 2 7 3
______________
9
```
Step 3: Move one column to the left (tens column) and add the digits. Here, we have 5 + 7, which equals 12. Since 12 is a two-digit number, write down 2 in the tens column and carry the 1 to the next column.
```
2 5 6
+ 1 2 7 3
______________
2 9
1 (carry)
```
Step 4: Move to the next column (hundreds column) and add the digits, including any carried numbers. In this case, 1 (carry) + 5 + 2 equals 8.
```
2 5 6
+ 1 2 7 3
______________
8 2 9
1 (carry)
```
Step 5: Move to the leftmost column (thousands column) and add the digits, including any carried numbers. Here, we only have the carried 1, so 1 equals 1.
```
2 5 6
+ 1 2 7 3
______________
1 8 2 9
1 (carry)
```
Step 6: Since there are no more columns to the left, we write down the final sum as 11829.
To determine the number of new groups (a new ten, a new hundred, a new thousand), refer to the place values of the numbers being added.
In this case, the units column does not exceed 9, so there are no new groups of ten. The tens column exceeds 9 (the sum is 12), so we have a new group of ten. The hundreds column does not exceed 99 (the sum is 8), so there are no new groups of a hundred. The thousands column does not exceed 999 (the sum is 1), so there are no new groups of a thousand.
Therefore, the answer is:
256 + 1273 = 11829
There is a new group of ten. There are no new groups of a hundred or a thousand.
