## Mastering Formulas, Tricks, and Shortcuts: Odd and Even Number Properties for GRE

In the world of GRE preparation, understanding the properties of odd and even numbers can be your secret weapon. The trick lies in recognizing patterns and applying straightforward formulas. Let’s unravel the mystery of these properties together.

### Formulas:

1. Addition/Subtraction: The result is always even when you add or subtract two odd numbers or two even numbers. However, the result is always odd when you add or subtract an odd and an even number.
2. Multiplication: Multiplying two odd numbers or an odd number and an even number always gives an odd result. However, multiplying two even numbers always gives an even result.

### Tricks and Shortcuts:

1. Recognizing Patterns: GRE questions involving odd and even numbers often revolve around recognizing patterns. For example, knowing that the sum of an odd number of odd numbers is odd can save valuable time.
2. Zero: Zero is an even number. This fact is often overlooked but can be crucial in solving GRE problems.
3. Negative Numbers: The properties of odd and even numbers also apply to negative numbers. So, -2, -4, -6, etc., are all even, and -1, -3, -5, etc., are all odd.
4. Last Digit Rule: If the last digit of a number is even (0, 2, 4, 6, 8), then the number is even. The number is odd if the last digit is odd (1, 3, 5, 7, 9).

Remember, understanding these concepts is only half the battle won. Applying them to solve problems within a given timeframe is what will truly set you apart in the GRE.

In the next section, we will share some general tips and time management strategies that will help you apply these formulas and tricks effectively.

## General Tips and Time Management Strategies for Odd and Even Number Properties in GRE

While understanding the concepts is critical, it’s equally important to know how to apply these concepts within the time constraints of the GRE. Here, we provide you with some general tips and time management strategies.

### General Tips:

1. Practice: As with all parts of the GRE, practice is key for odd and even number properties. Regular practice helps you identify patterns and apply formulas more quickly.
2. Understand the Question: Carefully read and understand the question before attempting it. Misinterpretation can lead to wrong answers, even with correct calculations.
3. Use Examples: If a question seems too abstract, use concrete examples. Plug in some odd and even numbers and observe the results.

### Time Management Strategies:

1. Master the Basics: Knowing the basic properties of odd and even numbers can save you precious time during the exam. Remember, every second counts.
2. Estimate: Not all questions require exact answers. Sometimes, estimating the answer can save time and get you close enough to the correct choice.
3. Skip Difficult Questions: Take your time with a hard question. It’s better to skip it initially and return to it later if time permits.
4. Use Scratch Paper: Use your scratch paper effectively. It’s a good place to jot down a sequence of odd or even numbers quickly, or to do quick computations.

Remember, speed and accuracy are of utmost importance in the GRE. You can ace this part of the GRE by understanding the properties of odd and even numbers and applying these strategies.

In the next section, we’ll take a look at some typical types of GRE questions that test your understanding of odd and even number properties.

Tackling Different Types of Questions: Odd and Even Number Properties in GRE

Applying the odd and even number properties, combined with effective time management, can help you tackle various types of GRE questions. Let’s look at some examples.

### Quantitative Comparison Questions:

Example: Compare the two quantities.

Quantity A: The sum of four consecutive even integers. Quantity B: The sum of four consecutive odd integers.

Solution: Remember the property that the sum of any two even or odd numbers is always even. Thus, the sum of four consecutive even integers or odd integers will be even. So, Quantity A is equal to Quantity B.

### Multiple-Choice Questions:

Example: Which of the following is the product of three odd integers?

A) 24 B) 27 C) 36 D) 45

Solution: Recall that the product of any number of odd integers is always odd. Therefore, the answer is D) 45, the only odd number in the options.

### Numeric Entry Questions:

Example: If ‘n’ is an even integer, what is the remainder when 3n+5 is divided by 2?

Solution: Remember that the sum of an even number and an odd number is odd. So, 3n (an even number, as n is even) + 5 (an odd number) results in an odd number. When any odd number is divided by 2, the remainder is always 1.

By understanding the properties of odd and even numbers and applying the strategies and tips we’ve discussed, you can tackle any GRE question that comes your way. Practice these concepts, and you’ll be well on your way to a great GRE score!
