The Function Table and the Rule

The video tutorial introduces the concept of recognizing patterns in numbers and explains how to use an input-output machine to apply mathematical rules. It demonstrates how to identify rules in function tables and solve problems using addition and subtraction. The tutorial also guides viewers on creating their own function tables by applying consistent rules.

What pattern is used to remember the phone number 1245780?

• Multiplying each digit by 2

• Skipping every third number

• Adding 1 to each digit

• Reversing the digits

In the input-output machine, if the input is 25 and the output is 35, what is the rule?

• Divide by 2

• Add 10

• Subtract 5

If the input is 28 and the output is 34, what rule is applied?

• Subtract 6

• Multiply by 2

• Divide by 2

• Add 6

When the input number is larger than the output number, what operation is typically used?

• Addition

• Subtraction

• Multiplication

• Division

In a function table where the rule is consistent, if the first input is 48 and the output is 43, what is the rule?

• Divide by 5

• Multiply by 5

• Subtract 5

• Add 5

What is the rule if you add 33 to 334 to get 367?

• Add 33

• Subtract 33

• Multiply by 33

• Divide by 33

If you create a function table with a rule of +5, what would be the output for an input of 10?

• 25

• 10
