Front

What is a function machine?

Back

A function machine is a conceptual tool used to describe a process where an input number is transformed into an output number using a specific rule.

Front

What does 'What's My Rule?' refer to in the context of function machines?

Back

'What's My Rule?' refers to the process of identifying the mathematical operation or rule that transforms an input into an output in a function machine.

Front

How do you find the missing number in a function machine?

Back

To find the missing number, you need to apply the identified rule to the known input or output.

Front

What is the rule if the output is 160 and the input is 200?

Back

The rule is to subtract 40 from the input.

Front

If the output is 20 and the input is 30, what is the rule?

Back

The rule is to subtract 10 from the input.

Front

What does it mean to 'subtract 10' in a function machine?

Back

It means that for any input number, you take away 10 to get the output.

Front

If the input is 85 and the output is 75, what is the rule?

Back

The rule is to subtract 10 from the input.

Front

What is the output if the input is 113 and the rule is to add 10?

Back

The output would be 123.

Front

How can you express the rule 'subtract 10' mathematically?

Back

Mathematically, it can be expressed as: output = input - 10.
