When comparing two integers the integer with the greater absolute value is always the greater integer?
No.A positive integer is always larger than a negative integer. In the case of two negative integers, the integer with the larger absolute value is actually smaller.
What are all negative integers greater than 6?
As 6 is a positive integer, no negative integer is greater than it.
Why is -1 the greatest negative integer?
There are no whole negative numbers greater than -1. Therefore, -1 is the highest negative whole integer. It can be thought of this way: When positive integers get larger, an amount is greater, but when negative integers get larger, the amount is less, so -1 is the greatest negative integer.
What are all integers that are greater than zero?
An integer is a whole number, with no decimal or fraction part. For example, 4 and 85 are integers. 3.9 and 1/2 are not integers. Greater than zero means positive numbers. Thus integers greater than zero are 1, 2, 3, 4 and so on.
Is the sum of integers always an integer?
Yes, by definition, the sum of two integers is always an integer. Likewise, the product and difference of two integers is always an integer.
What is a positive integer and what is a negtive integer?
Positive integers are greater than zero. Negative integers are less than zero.
When comparing two integers the integer with the greater absolute value is always the greater integer?
No.A positive integer is always larger than a negative integer. In the case of two negative integers, the integer with the larger absolute value is actually smaller.
What are all negative integers greater than 6?
As 6 is a positive integer, no negative integer is greater than it.
When comparing two integers the integer with the bigger absolute value is always the greater integer?
The statement is false.
How do you determine the value of one integer in comparison to the value of another integer?
Look at the places that integers have on the number line. The integer that is on the right is greater that the integer is on the left.
What are the odd integers greater than 40?
Any integer that is divisible by 2 with no remainder is even otherwise it is an odd integer
What integers when added to -7 give a sum greater than 0?
Any integer greater than +7.
Why is -1 the greatest negative integer?
There are no whole negative numbers greater than -1. Therefore, -1 is the highest negative whole integer. It can be thought of this way: When positive integers get larger, an amount is greater, but when negative integers get larger, the amount is less, so -1 is the greatest negative integer.

Can integers be square roots?
Of course they can. Every integer greater than zero is a square root.
Is a to the 3rd power greater than or equal to a for all integer values of A and why?
No. A negative integer raised to the third power will yield a negative number that is less than the integer. Only whole numbers (positive integers greater than or equal to 1) have the property where that integer raised to the third power is greater than or equal to the integer.
What are all integers that are greater than zero?
An integer is a whole number, with no decimal or fraction part. For example, 4 and 85 are integers. 3.9 and 1/2 are not integers. Greater than zero means positive numbers. Thus integers greater than zero are 1, 2, 3, 4 and so on.
