Answer:
regrouping: 1 1
first addend: 2 8 7
second addend: 5 6
sum: 3 4 3
Step-by-step explanation:
first: add the digits in the ones column
2 8 7
+ 5 6
13
because the answer is two digits, you leave the digit in the ones space in the answer, and move the digit in the tens space to the regrouping area above the tens column in the problem. it should look like this:
1
2 8 7
+ 5 6
3
then add the digits in the tens column. you also add the regrouped number.
1
2 8 7
+ 5 6
14 3
once again, the answer is two digits, so you repeat the same process, except since the digits are already in the tens place, you move the first digit above the hundreds place:
1 1
2 8 7
+ 5 6
4 3
add the hundreds column:
1 1
2 8 7
+ 5 6
3 4 3
this is you answer
have a wonderful day <3
