explain how to do subtractions using burrowing
Answers
Step-by-step explanation:
Borrowing is a two-step process:
Subtract 1 from the top number in the column directly to the left. Cross out the number you're borrowing from, subtract 1, and write the answer above the number you crossed out.
Add 10 to the top number in the column you were working in.
Answer:Hi!!!!!
Step-by-step explanation:Subtract 1 from the top number in the column directly to the left.
1)Cross out the number you’re borrowing from, subtract 1, and write the answer above the number you crossed out.
2)Add 10 to the top number in the column you were working in.
For example, suppose you want to subtract 386 – 94. The first step is to subtract 4 from 6 in the ones column, which gives you 2:
When you move to the tens column, however, you find that you need to subtract 8 – 9. Because 8 is smaller than 9, you need to borrow from the hundreds column. First, cross out the 3 and replace it with a 2, because 3 – 1 = 2:
Next, place a 1 in front of the 8, changing it to an 18, because 8 + 10 = 18:
Now you can subtract in the tens column: 18 – 9 = 9:
The final step is simple: 2 – 0 = 2:
Therefore, 386 – 94 = 292.
Hope you get answer..
