What does it mean to 'borrow' in subtraction?

Back

Borrowing in subtraction refers to the process of taking 1 from the next higher place value to help subtract a larger digit from a smaller digit in the current place value.

Front

What is regrouping in subtraction?

Back

Regrouping in subtraction is the process of rearranging numbers to make the subtraction easier, often involving borrowing from the next column.

How do you determine the rule in an input/output table?

Back

To determine the rule in an input/output table, look for a consistent pattern or operation that relates the input values to the output values.

What is the result of subtracting 4 from a number?

Back

Subtracting 4 from a number means to take away 4 from that number, resulting in a smaller value.

Front

If the input is 10 and the rule is 'minus 4', what is the output?

If the input is 10 and the rule is 'minus 4', the output is 6.

Front

What are the steps to solve a subtraction problem with borrowing?

Back

1. Identify the digits in each place value. 2. If the top digit is smaller than the bottom digit, borrow from the next column. 3. Subtract the digits. 4. Write down the result.

Front

What is the significance of missing numbers in an input/output table?

Back

Missing numbers in an input/output table indicate values that need to be calculated based on the established rule.

Front

How can you find missing numbers in a subtraction problem?

Back

To find missing numbers in a subtraction problem, you can use the known values and the operation to work backward.

Front

What does the term 'rule' refer to in the context of input/output tables?

Back

In the context of input/output tables, the 'rule' refers to the mathematical operation or relationship that connects the input values to the output values.
