• + 28975


• ------


• 52487

• Add the rightmost digits: 2 + 5 = 7


• Add the next digits: 1 + 7 + 9 = 17, write down 7 and carry over 1


• Add the next digits: 3 + 8 + 1 = 12, write down 2 and carry over 1


• Add the leftmost digits: 2 + 2 = 4

Therefore, 23512 + 28975 = 52487

• Start by adding the ones place digits: 4 + 0 = 4


• Move to the tens place: 8 + 0 = 8


• Now add the hundreds place: 0 + 9 = 9


• Finally, add the thousands place: 8 + 2 = 10

• Our sum is 10 (thousands), 9 (hundreds), 8 (tens), 4 (ones)


• Therefore, 8084 + 2900 = 10984

• 10984

• Statement A: The answer in addition is called sum.


• Statement B: The answer in addition is called difference.
