Utilizing Parentheses with Fractions
Importance of using parentheses when performing operations with fractions involving other operators
When working with fractions on the TI-84 Plus calculator, it is crucial to understand how to use parentheses to ensure the correct order of operations. The use of parentheses becomes particularly important when performing operations with fractions involving other operators such as addition, subtraction, multiplication, and division.
Using parentheses correctly helps clarify the intended order of operations and prevents any confusion or errors that might arise. Without the use of parentheses, the calculator may prioritize certain operations over others, leading to incorrect results.
For example, consider the expression (2/3) + (4/5) * (7/8). Without using parentheses, the calculator may apply the multiplication first, resulting in (2/3) + (0.8) = 2.6/3. However, the correct order of operations requires adding the fractions before multiplying, which gives a different answer of 89/120.
To ensure the proper order of operations and obtain accurate results when working with fractions, follow these steps:
1. Identify the operations and determine the order in which they should be performed.
2. Enclose each fraction and the operation involving that fraction within parentheses.
Using the previous example, the correct expression with parentheses would be ((2/3) + (4/5)) * (7/8). This ensures that the addition is performed first, giving the sum of 22/15, and then the multiplication is carried out, resulting in 77/60.
By utilizing parentheses correctly, you can avoid any confusion or errors that may arise when working with fractions on the TI-84 Plus calculator. This practice ensures that the calculator carries out the operations in the desired order, providing accurate results for your calculations.
Remember to consistently use parentheses whenever working with fractions and other operators to maintain clarity and achieve accurate solutions.
