Answer 1

To efficiently subtract multi-digit numbers, start by lining up the numbers vertically so that each digit is in its respective column (ones under ones, tens under tens, etc.). Then, begin subtracting from the rightmost column (the ones place) and move left. If the top digit is smaller than the bottom digit, you'll need to borrow from the next column to the left. This means decreasing the top digit by 1 and adding 10 to the current digit you're subtracting from. Continue this process for each column until you've completed the subtraction for all digits. Finally, if there are any remaining columns on the top that don’t need to be borrowed from, just write those down as they are. This way, you'll get the correct answer systematically and easily.
