Full solution

Q. 20722072 to 97149714
  1. Line up numbers vertically: First, we line up the numbers vertically with the larger number on top:\newline\newline\begin{align*}\newline&\phantom{+}97149714(\newline\)&+20722072(\newline\)\end{align*}\newline\newlineNow we add the numbers starting from the rightmost digit.
  2. Add ones place: Adding the ones place: 4+24 + 2 equals 66.
  3. Add tens place: Adding the tens place: 1+71 + 7 equals 88.
  4. Add hundreds place: Adding the hundreds place: 7+07 + 0 equals 77, but oops, I made a mistake here, it should be 7+07 + 0 equals 77, so no error actually.
  5. Add thousands place: Adding the thousands place: 9+29 + 2 equals 1111, so we write down 11 and carry over the 11 to the next place.
  6. Carry over: Since there are no more digits to add to the left, we just bring down the 11 that we carried over.
  7. Bring down: The final answer is 1178611786.
