Subtracting with borrowing

Front

What is borrowing in subtraction?

Back

Borrowing in subtraction is a method used when the digit in the minuend (the number from which another number is subtracted) is smaller than the digit in the subtrahend (the number that is being subtracted). It involves taking 1 from the next higher place value.

How do you subtract 16 - 9 using borrowing?

Back

To subtract 16 - 9, you can think of it as 16 being 10 + 6. You can borrow 1 from the 10, making it 9, and add 10 to the 6, making it 16. Then, 16 - 9 = 7.

Explain the process of subtracting 529 - 361.

Back

To subtract 529 - 361, start from the rightmost digit. 9 - 1 = 8, 2 - 6 requires borrowing, so it becomes 12 - 6 = 6, and 4 - 3 = 1. Thus, 529 - 361 = 168.

How do you subtract 90 - 15?

Back

To subtract 90 - 15, you can think of it as 90 being 80 + 10. Borrow 1 from the 80, making it 79, and add 10 to the 10, making it 20. Then, 20 - 5 = 15 and 79 - 1 = 7. Thus, 90 - 15 = 75.

Front

What is the term for the number being subtracted from?

Back

The term for the number being subtracted from is called the 'minuend'.

Front

What is the term for the number that is being subtracted?

Back

The term for the number that is being subtracted is called the 'subtrahend'.

Front

What does it mean to regroup in subtraction?

Back

Regrouping in subtraction means rearranging the digits in the minuend to make it easier to subtract, often involving borrowing from the next higher place value.

Front

What is the first step in subtracting 100 - 47?

Back

The first step in subtracting 100 - 47 is to look at the rightmost digits. Since 0 is less than 7, you need to borrow from the next place value.
