Eureka Math Grade 4 Module 1 Topic E Flashcard

Front

What is the process of subtraction in mathematics?

Back

Subtraction is the mathematical operation of finding the difference between two numbers, where one number is taken away from another.

Front

How do you subtract large numbers effectively?

Back

To subtract large numbers, align the numbers by their place values (units, tens, hundreds, etc.) and subtract each column starting from the rightmost column, borrowing from the next column if necessary.

Front

What is borrowing in subtraction?

Back

Borrowing is a technique used in subtraction when the digit in the top number is smaller than the digit in the bottom number in a given column. You 'borrow' from the next left column to make the subtraction possible.

Front

What is the difference between the terms 'minuend' and 'subtrahend'?

Back

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

Front

How do you check your subtraction work?

Back

To check subtraction, you can add the difference to the subtrahend. If the sum equals the minuend, your subtraction is correct.

Front

What is an application-based question in mathematics?

Back

An application-based question requires students to apply mathematical concepts to real-world scenarios, often involving problem-solving and critical thinking.

Front

How can you represent subtraction visually?

Back

Subtraction can be represented visually using number lines, counters, or diagrams that show the removal of a quantity from a total.

Front

What is the importance of understanding place value in subtraction?

Back

Understanding place value is crucial in subtraction as it helps in aligning numbers correctly and performing operations accurately across different columns.

Front

What is the result of subtracting a larger number from a smaller number?

Back

Subtracting a larger number from a smaller number results in a negative number, indicating that the minuend is less than the subtrahend.

Front

How do you solve word problems involving subtraction?

Back

To solve word problems involving subtraction, identify the quantities involved, determine what is being subtracted, and set up a mathematical equation to find the answer.
