Addition
Addition can be done using any kind of positive number in the mathematical world. We start learning addition using small or single-digit numbers, but it can be done with larger numbers as well. But before going to large numbers, one must know these simple steps for addition.
The steps are as follows:
- The first step is to stack the numbers according to their place value.
- The second step is to add the numbers starting from the right side of the column.
- If there are carry numbers, then that will go to the left-hand side as needed. This process should be continued if there are many numbers to be calculated.
Here is an example
For the first day of a cricket match, 23,456 tickets were sold, while 14,978 tickets were sold for the second day. How many tickets were sold in all?
2 3 4 5 6
+ 1 4 9 7 8
3 8 4 3 4
The total number of tickets sold was 38,434.
