What is an Input/Output Table?

Back

An Input/Output Table is a mathematical tool used to show how one set of numbers (inputs) relates to another set of numbers (outputs) through a specific rule.

What does the term 'rule' mean in an Input/Output Table?

Back

The 'rule' is the operation or mathematical process applied to the input to get the output, such as adding, subtracting, multiplying, or dividing.

Front

If the rule is 'Add 6', what is the output when the input is 4?

Back

The output is 10, because 4 + 6 = 10.

Front

If the rule is 'Multiply by 3', what is the output when the input is 5?

Back

The output is 15, because 5 x 3 = 15.

Front

What two numbers are missing if the inputs are 1, 2, 3 and the outputs are 4, 5, ?

Back

The missing output is 6, because the rule is 'Add 3'.

Front

How do you find a missing input in an Input/Output Table?

Back

To find a missing input, you can reverse the rule applied to the output.

Front

What is the output if the input is 10 and the rule is 'Subtract 6'?

Back

The output is 4, because 10 - 6 = 4.

Front

What is the output if the input is 8 and the rule is 'Divide by 2'?

Back

The output is 4, because 8 ÷ 2 = 4.

Front

If the rule is 'Subtract 2', what is the output when the input is 7?

Back

The output is 5, because 7 - 2 = 5.

Front

What is the rule if the inputs are 2, 4, 6 and the outputs are 8, 10, 12?

Back

The rule is 'Add 6'.
