FAQs on Ordering and Comparing Integers

1. What are integers and how are they different from whole numbers?
Ans. Integers are a set of numbers that include all positive whole numbers, negative whole numbers, and zero. They differ from whole numbers, which include only the positive integers and zero, excluding negative numbers.
2. How can I compare two integers?
Ans. To compare two integers, you can look at their value. If one integer is greater than the other, it is indicated with the 'greater than' sign (>), while if it is less, it uses the 'less than' sign (<). If they are equal, the 'equal to' sign (=) is used.
3. What is the process for ordering a set of integers from least to greatest?
Ans. To order a set of integers from least to greatest, first identify the smallest integer in the set. Then, compare the remaining integers sequentially to determine their order, placing them in a line from the smallest to the largest.
4. Can negative integers be greater than positive integers?
Ans. No, negative integers cannot be greater than positive integers. Negative integers are always less than zero, while positive integers are greater than zero, making all positive integers greater than any negative integer.
5. How do I add and subtract integers when they have different signs?
Ans. When adding integers with different signs, subtract the smaller absolute value from the larger absolute value and keep the sign of the integer with the larger absolute value. For subtraction, change the sign of the integer being subtracted and then follow the same rules as addition.
