00:03 Each time consider a shortage of 2 digits, and then we'll place
00:07 1 less than 2
00:11 We want to borrow from the larger digits
00:15 Both tens and hundreds equal 0 so we'll borrow from thousands
00:19 What will change the thousands from 2 to 1
00:22 And now we'll have 10 instead of 0, in hundreds!
00:25 And we'll borrow from hundreds to tens
00:29 We'll have 10 in tens, and 9 in hundreds
00:32 And we'll continue with the same method, borrowing from tens to ones
00:35 We'll have 11 in ones, and 9 in tens
00:42 Subtract ones from ones, and place in ones
00:47 Subtract tens from tens, and place in tens

Step-by-step solution

To solve the problem of subtracting 1542 from 12001, we will perform vertical subtraction, borrowing where necessary:

  • Step 1: Align the numbers by place value:

  •    1200101542 \begin{array}{c} ~~~12001 \\ - \phantom{0} 1542 \\ \hline \end{array}

  • Step 2: Start subtracting from the rightmost digit (ones place):

  • The ones column requires borrowing since 1<21 < 2. Borrow from the tens.

  • The tens column is 0, so we need to borrow from the hundreds. The hundreds column is also 0, so we move to the thousands. The thousands column has 2, which becomes 1, and the hundreds column becomes 10, and then the tens column becomes 9. The ones column becomes 11.

  • Now subtract: Ones column: 112=911 - 2 = 9

  • Step 3: Move to the tens place: Subtract 94=59 - 4 = 5

  • Step 4: Move to the hundreds place: Subtract 95=49 - 5 = 4 after borrowing.

  • Step 5: Move to the thousands place: Subtract 11=01 - 1 = 0

  • Step 6: Finally, in the ten-thousands: Note that 11 merely moves down as there’s no digit to deduct.

Putting it all together:

   1200101542   10459 \begin{array}{c} ~~~ 12001 \\ - \phantom{0}1542 \\ \hline ~~~10459 \\ \end{array}

Therefore, the final solution to the problem is 10459 10459 .
