To solve the given equation:
27289347474747484920102 - 2828393930339392939393929
Step 1: Subtract the numbers vertically column by column, starting from the rightmost column (ones place).
2 - 9 = -7 (since 2 is smaller than 9, borrow 10 from the next column; therefore, 2 becomes 12 and subtracting 9 gives 3 in the ones place)
Step 2: Continue subtracting in each column.
1 - 2 = -1 (borrow 10 again and make 1 as 11 and subtracting 2 gives 9)
0 - 3 = -3 (borrow 10 again and make 0 as 10 and subtracting 3 gives 7)
Step 3: Carry the negative sign and subtract the remaining numbers.
-4 - 9 = -13 (borrow 10 again and make -4 as 6 and subtracting 9 gives -3)
Step 4: Continue subtracting in each column.
7 - 3 = 4
Step 5: Carry the negative sign and subtract the remaining numbers.
-3 - 9 = -12
The final result is:
27289347474747484920102 - 2828393930339392939393929 = -24954641971934541304016
