Final answer:
The order of precedence in a formula can be controlled using parentheses.
Step-by-step explanation:
The correct answer is a) True.
In a formula, the order of precedence determines the sequence in which operations are performed. By using parentheses, you can control the order of operations and specify which calculations should be performed first. This can be particularly helpful when dealing with complex formulas that involve multiple operations.
For example, consider the following formula: a + b / c * d. Without parentheses, the order of operations would be: division, multiplication, and then addition. However, if you want to perform the addition before the division, you can use parentheses to prioritize it: (a + b) / c * d.
