Solve Vertical Subtraction: 7189 minus 2392

Video Solution

Solution Steps

00:00 Solve

00:03 Each time subtract 2 digits, and then we'll place

00:06 Subtract ones from ones, and place in ones

00:09 8 is less than 9

00:14 Therefore we subtract 1 from hundreds, and add this amount to tens

00:19 That means now instead of 8 we'll have 18

00:24 Subtract tens from tens plus the ten

00:28 Place in tens

00:34 0 is less than 3

00:38 Therefore we subtract 1 from thousands, and add this amount to hundreds

00:45 That means now instead of 0 we'll have 10

00:49 Subtract hundreds from hundreds plus the hundred

00:53 Place in hundreds

00:56 Subtract thousands from thousands, and place in thousands

00:59 And this is the solution to the question

Step-by-Step Solution

To solve this problem, we'll use the vertical subtraction method, breaking down the problem into each column from right to left:

Tens: As $8 - 9$ is not possible, regroup by borrowing 1 from the hundreds column, making it $18 - 9 = 9$ .

After borrowing, the hundreds column has $0 - 3$ (as it was reduced from 1), borrow from the thousands column: $10 - 3 = 7$ .

Putting it all together, we find that:

$7189 - 2392 = 4797$ .

The correct answer is $4797$ .
