Is a negative integer times a negative integer equal to a positive integer?
Yes, and also a negative integer divided by a negative integer is equal to a positive number (but not necessarily an integer).
Does the sum of a negative integer and a positive integer always zero?
No,because if you add -5 and 10 you get 5 which is not equal to zero. They way you would get 0 as an answer is if you add a negative integer and it's opposite like -5 and 5. Then your answer would be zero.
Does a positive integer multiplied by a negative integer equal a negative integer?
All negative integers, when multiplied by a positive integer, or vice versa, will result in a negative integer. I. E. 5*-5=-25
When does a positive integer and a negative integer equal a positive integer?
When they are added together and the absolute value of the positive integer is bigger than the absolute value of the negative integer or when the negative integer is subtracted from the positive integer.
What is the opposite of the opposite of an integer?
The opposite valueTo find the opposite value of an integer, you simply change it to negative if it is positive, or change it to positive if it is negative. This is the additive inverse.Another opposite valueTo find the opposite value of an integer, you simply make it the denominator of a fraction and use 1 for the numerator. This is the multiplicative inverse.An opposite viewThere isn't really an opposite of an integer - there are many types of numbers that aren't integers.An integer is a 'whole number' - like 6, -5, or 1029687.Another type of number is a rational number, also known as a 'fraction' or 'decimal'. Examples would be 3.4, 5 1/2, -8.9925.Then there are irrational numbers, which are numbers that can't be written as a fraction, and when you write them as a decimal they go on infinitely without a repeating pattern. Examples are the numbers pi (which is approximately equal to 3.14159), e (approx. equal to 2.71828).Then there are imaginary numbers, which are equal to the square root of a negative number. The basic imaginary number is i, which is equal to the square root of -1.
