Exploring Input and Output Tables: Addition and Subtraction

In this video, Mr. J explains how to work with input and output tables involving addition and subtraction. He provides four examples, demonstrating how to determine the rule for each table and fill in missing values. The video covers both horizontal and vertical tables, emphasizing the importance of identifying whether to add or subtract to find the correct output.

What operation is used to transform the input to the output in the first example?

• Addition

• Subtraction

• Multiplication

• Division

How much is subtracted from the input to get the output in the first example?

• 7

• 6

• 3

• 5

What is the correct output for an input of 13 in the first example?

• 5

• 3

• 18

• 8

What is added to each input to find the output in the second example?

• 15

• 10

• 7

• 5

In the second example, what input value gives an output of 12?

• 5

• 6

• 7

• 8

In the third example, what is the rule for transforming the input to the output?

• Input minus 15

• Input plus 10

• Input plus 15

• Input minus 10

What is the missing input if the output is 64 in the third example?

• 49

• 50

• 79

• 34

In the final example, how much is subtracted from the input to achieve the output?

• 5

• 6

• 7

• 8

What is the output when the input is 8 in the final example?

• 6

• 14

• 2

• 3

Which operation is not used in any of the examples?

• Multiplication
