Subtraction of Two-Digit Numbers

In subtracting two-digit numbers, we have to use vertical subtraction for an easier solving process. To arrange numbers vertically for subtraction, we must put them according to their place value. Like for example, 23 minus 17. We need to put it vertically aligned to their respective place value, 3 and 7 are ones while 2 and 1 are tens. Now that we have them lined up, we could now proceed to subtract them from each other. Each column has its own place value, and we can only subtract numbers from the same column and place value. In our example, we can only subtract 7 from 3 and 1 from 2. Since we can’t subtract 7 from 3, because 3 is less than 7, we are going to borrow from the next column to make 3 a bigger number and that is from 2 with the tens value. When borrowing from another number, we take one number from it and add it to the column we are working at. But the thing about borrowing is that, when you add the borrowed number from tens to ones, the value of the number will be 10. So, if we borrow from 2 and put it to 3, it will become 1 and 13, respectively. Now, we can subtract 7 from 13 which will give us 6 and when we subtract the numbers in the tens column, we will be left with zero. Hence, the difference between the subtraction of the two-digit numbers, 23 and 17 is 6.
