Introduction

Mathematical expressions can often be unclear or difficult to read, especially when they involve multiple operations or complex calculations. In this article, we will explore how to reformat mathematical expressions for clarity, using real-world examples to illustrate the importance of clear notation.

Reformatting Division Expressions

Division expressions can be particularly tricky to read, especially when the dividend and divisor are large numbers. To make these expressions clearer, we can use a variety of techniques, including:

Using parentheses: By adding parentheses around the dividend and divisor, we can make it clear which numbers are being divided.
Using a horizontal bar: A horizontal bar can be used to separate the dividend and divisor, making it easier to read.
Using a fraction bar: A fraction bar can be used to represent the division operation, making it clear that we are dealing with a fraction.

Let's take a look at some examples of reformatting division expressions:

Example 1: Reformatting $3 \div 51$

The original expression is: $3 \div 51$

To reformat this expression, we can use parentheses to make it clear which numbers are being divided:

$ \frac{3}{51} $

Alternatively, we can use a horizontal bar to separate the dividend and divisor:

$ 3 \ \overline{51} $

Example 2: Reformatting $7 \div 91$

The original expression is: $7 \div 91$

To reformat this expression, we can use parentheses to make it clear which numbers are being divided:

$ \frac{7}{91} $

Alternatively, we can use a horizontal bar to separate the dividend and divisor:

$ 7 \ \overline{91} $

Example 3: Reformatting $5 \div 65$

The original expression is: $5 \div 65$

To reformat this expression, we can use parentheses to make it clear which numbers are being divided:

$ \frac{5}{65} $

Alternatively, we can use a horizontal bar to separate the dividend and divisor:

$ 5 \ \overline{65} $

Example 4: Reformatting $7 \div 89$

The original expression is: $7 \div 89$

To reformat this expression, we can use parentheses to make it clear which numbers are being divided:

$ \frac{7}{89} $

Alternatively, we can use a horizontal bar to separate the dividend and divisor:

$ 7 \ \overline{89} $

Reformatting Square Root Expressions

Square root expressions can also be tricky to read, especially when the radicand is a large number. To make these expressions clearer, we can use a variety of techniques, including:

Using a square root symbol: By using a square root symbol (√) to represent the square root operation, we can make it clear that we are dealing with a square root.
Using parentheses: By adding parentheses around the radicand, we can make it clear which number is being taken as the square root.
Using a fraction bar: A fraction bar can be used to represent the square root operation, making it clear that we are dealing with a fraction.

Let's take a look at some examples of reformatting square root expressions:

Example 5: Reformatting $2 \sqrt{77}$

The original expression is: $2 \sqrt{77}$

To reformat this expression, we can use a square root symbol to represent the square root operation:

$ 2 \sqrt{77} $

Alternatively, we can use parentheses to make it clear which number is being taken as the square root:

$ 2 \left( \sqrt{77} \right) $

Example 6: Reformatting $4 \sqrt{47}$

The original expression is: $4 \sqrt{47}$

To reformat this expression, we can use a square root symbol to represent the square root operation:

$ 4 \sqrt{47} $

Alternatively, we can use parentheses to make it clear which number is being taken as the square root:

$ 4 \left( \sqrt{47} \right) $
