8-5 Practice

Front

What is a rule in a mathematical table?

Back

A rule in a mathematical table describes the relationship between the input and output values, often expressed as an equation or a pattern.

Front

How do you find a missing number in a table?

Back

To find a missing number in a table, identify the pattern or rule that connects the known numbers, and apply it to determine the unknown value.

Front

What does it mean to write an expression for a rule?

Back

Writing an expression for a rule means creating a mathematical statement that represents the relationship between variables, such as 't + $30' or 'p x $30'.

Front

What is the difference between addition and multiplication in rules?

Back

Addition combines values to increase the total, while multiplication scales a value by a factor, often resulting in a larger output.

Front

What is an example of a simple addition rule?

Back

An example of a simple addition rule is: If the input is 5, the output is 5 + 3 = 8.

Front

What is an example of a multiplication rule?

Back

An example of a multiplication rule is: If the input is 4, the output is 4 x 2 = 8.

Front

How can you express a rule using variables?

Back

You can express a rule using variables by substituting letters for numbers, such as 'x + 5' or '2y'.

Front

What is a missing number problem?

Back

A missing number problem requires you to find an unknown value in a sequence or table based on a given pattern or rule.

Front

What is the significance of patterns in mathematics?

Back

Patterns help identify relationships between numbers, making it easier to predict future values and solve problems.

Front

How do you verify a rule in a table?

Back

To verify a rule in a table, check if the rule holds true for all known input-output pairs.
