4.5 B Input/Output Tables Day 2

Front

What is an input/output table?

Back

An input/output table is a mathematical tool that shows the relationship between input values (numbers you put in) and output values (results you get).

Front

How do you find the output number using a rule?

Back

To find the output number, you apply a specific rule (like +19 or -2) to the input number.

Front

What does the rule +19 mean in an input/output table?

Back

The rule +19 means that you add 19 to the input number to get the output number.

Front

If the input number is 5 and the rule is -2, what is the output?

Back

The output is 3, because 5 - 2 = 3.

Front

What is a number machine in mathematics?

Back

A number machine is a way to visualize how input numbers are transformed into output numbers using a specific rule.

Front

If the input is 10 and the output is 8, what rule could be used?

Back

The rule could be -2, because 10 - 2 = 8.

Front

What is the output if the input is 4 and the rule is x2?

Back

The output is 8, because 4 x 2 = 8.

Front

How can you determine the output for the 16th position in a pattern?

Back

You can find the output by identifying the pattern and applying it to the 16th position.

Front

What does the rule x5 mean in an input/output table?

Back

The rule x5 means that you multiply the input number by 5 to get the output number.

Front

If the input is 3 and the rule is +20, what is the output?

Back

The output is 23, because 3 + 20 = 23.
