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.

False. Counterexample: -1 - (-2) = -1 + 2 = 1.

True, an example of this is 1 - 2 = -1 1 - -------2 is = to -15000 fact

That would be false. When you subtract two positive numbers, you only go into negatives if the number you are subtracting is greater than the number it's being subtracted from. 3 - 2 = 1 2 - 3 = -1

That is false. A negative times a negative is always a positive. Since absolute numbers are always positive if you make it negative that is not correct.

That is false. The product of two negative integers is always positive.

An integer is a whole number (not a fractional number) that can be positive, negative or zero - so true

yes the answer is always a positive

Largest negative integer-1 true or false

No. You have it backwards . . . . . the absolute value of a negative number is always a positive number.

Yes, multiplying a Positive value by a Negative value always yields a Negative product.

False.

you can have a false negative but NOT a false positive

Is false. If ' n ' is negative, then ' -n ' is positive.

False. Either the product or the quotient of two negative numbers is positive.False. Either the product or the quotient of two negative numbers is positive.False. Either the product or the quotient of two negative numbers is positive.False. Either the product or the quotient of two negative numbers is positive.

The absolute value will always be positive because if you think about it, the absolute value.

False. Chloride (Cl-) is a monoatomic ion with a negative charge.

False. The natural numbers are the counting numbers: 1, 2, 3, ... which are the positive integers; -7 is a negative integer and so not one of them.

False - if the sentence is meant to be exhaustive. Integers can be positive or negative OR ZERO.

It is not possible with 1 test to have both positive and negative. It is possible, but NOT likely, to get a false positive or false negative on a test.

I don't know about chromophores, but anions are always negative and cations are always positive. The way my teacher had us remember is that 'cat'ions are always 'paw'sative.

The rates of false negative and false positive chlamydia tests for various types of tests are as follows (see related link):Chlamydia culture (rarely done): 0% false positive, 15-30% false negative.Swab with DFA: less than 1% false positive; 15-20% false negativeBecton-Dickinson NAAT cervical swab: 1.9% false positive, 10.3% false negativeBecton-Dickinson NAAT female urine: 1% false positive; 19.5% false negativeBecton-Dickinson NAAT male urine: 1.6% false positive 5.5% false negativeGen Probe NAAT cervical swab: 1.9% false positive; 5.8% false negativeGen Probe NAAT vaginal swab (e.g. self administered): 1.6% false positive; 3.3% false negativeGen Probe NAAT female urine: 1.1% false positive; 5.3% false negativeGen Probe NAAT male urine: 0.9% false positive; 3% false negative

That statement is false. For example, (-2) - (-3) = 1 which is a positive number created from two negative numbers when subtracted.
