What are integers?

Integers are whole numbers that can be positive, negative, or zero, and do not have any fractional or decimal parts. They include numbers such as 0, 1, -1, 2, -2, and so on, and are used in mathematics to represent quantities that do not have fractional values.

How do you represent positive and negative integers on a number line?

Positive integers are represented to the right of zero on a number line, with increasing values as you move further to the right. Negative integers are represented to the left of zero on a number line, with decreasing values as you move further to the left. Zero is located at the center of the number line, acting as the origin point where positive and negative integers meet.

Can you add two negative integers together? If so, what is the result?

Yes, you can add two negative integers together. When you add two negative integers, the result is another negative integer. The sum of two negative integers will be the sum of their absolute values with a negative sign. For example, -3 + (-5) would be -8.

What is the rule for subtracting integers?

When subtracting integers, you can simply add the opposite. That means subtracting a positive integer is equivalent to adding a negative integer, and subtracting a negative integer is equivalent to adding a positive integer. So, to subtract integers, change the subtraction sign to addition and change the sign of the integer being subtracted.

Can you multiply two negative integers? If so, what is the result?

Yes, you can multiply two negative integers. When you multiply two negative integers, the result is a positive integer. For example, (-2) * (-3) = 6.

How do you divide integers?

To divide integers, you follow the same rules as division with whole numbers. You divide the numerator by the denominator and determine the quotient, which may result in a whole number, a fraction, or a decimal. Remember to consider the signs of the integers involved in the division to determine the sign of the quotient following the rules of positive/negative integer division.

How do you compare integers using inequality symbols?

When comparing integers using inequality symbols, you can use the symbols ">" for greater than, "<" for less than, ">=" for greater than or equal to, and "<=" for less than or equal to. For example, 5 > 3 would mean that 5 is greater than 3, while 4 <= 4 would mean that 4 is less than or equal to 4. Just remember that when comparing integers, the inequality symbols help you determine the relationship between the numbers based on their magnitudes.

What is absolute value and how is it related to integers?

The absolute value of a number is its distance from zero on the number line, regardless of its sign. It is always positive or zero. In the context of integers, the absolute value of an integer is itself if the integer is non-negative and its negative if the integer is negative. For example, the absolute value of -3 is 3. Absolute value is often used in mathematical operations involving integers, such as finding the difference between two integers or solving equations with absolute value expressions.

How do you solve equations involving integers?

To solve equations involving integers, you would need to follow basic algebraic principles such as using inverse operations to isolate the variable. By performing the same operation on both sides of the equation, you can simplify and find the value of the variable, making sure to maintain integer values throughout the process. Substitution, rearranging terms, and simplifying expressions are also common techniques used to solve equations involving integers.

How can integers be applied to real-life scenarios or problem-solving situations?

Integers can be applied to real-life scenarios or problem-solving situations in various ways, such as keeping track of inventory, calculating profit or loss in business transactions, measuring distances or temperatures, and representing quantities in everyday tasks like budgeting or time management. By using integers, one can efficiently capture and manipulate whole numbers in these situations, allowing for precise calculations and decision-making processes.
