What is a minuend in subtraction?

Back

The minuend is the number from which another number (the subtrahend) is to be subtracted.

What is a subtrahend in subtraction?

Back

The subtrahend is the number that is to be subtracted from another number (the minuend).

What is the difference in subtraction?

Back

The difference is the result of a subtraction operation. For example, in the expression 10 - 4, the difference is 6.

Front

What is the relationship between addition and subtraction?

Back

Addition and subtraction are inverse operations. If you add a number and then subtract the same number, you return to the original number.

How can subtraction be visualized?

Back

Subtraction can be visualized using objects, number lines, or diagrams. For example, if you have 5 apples and take away 2, you can visually represent this by removing 2 apples from a group of 5.

What is borrowing in subtraction?

Back

Borrowing is a technique used in subtraction when the digit in the minuend is smaller than the digit in the subtrahend. It involves taking 1 from the next higher place value.

What is the importance of place value in subtraction?

Back

Place value is crucial in subtraction as it determines how numbers are aligned and subtracted, especially in multi-digit subtraction.
