Interesting..
I've had the same thing happen to me (minus the ultrasound...) in getting several false positives.
However, mine were due to having cysts on my ovaries- which are known for affecting the result of home pregnancy tests. If you're still uncertain, I'd try taking a blood test; it is possible that if you are indeed pregnant, the pregnancy is too young to be shown in an ultrasound.
Negative * positive = negative Positive * positive = positive Negative * negative = positive
The answer is always positive. If the signs are the same (positive by positive, negative by negative), then the quotient is always positive. If the signs are different (positive by negative, negative by positive), then the quotient is always negative.
a(-)and a(-)=positive a(+)and a(+)=positive but a(-)and a(+) or a(+)and a(-)= negative so two signs the same is positive and two signs that are different are negative.
Signs of pregnancy are the same in all patients. A missing period and positive pregnancy tests are signs of pregnancy.
Positive x Positive = Positive Negative x Negative = Positive Positive x Negative = Negative Basically if the signs are the same, the answer will always be positive, and if the signs are different the answer will be negative. Hope this helps.
see if have -8 divided by -8 divide the number number first and then see to the following signs-8 divided by -8 is equal to +1-8 divided by +8 is equal to -1so different signs -same sign +++=+--=++-=--+=-
Yes. A negative subtracted by a negative is a positive. Just remember that two like signs become a positive sign, and two unlike signs become a negative sign.
if the 2 signs are negative, than the sum is negative. if the 2 signs are positive, than the sum is positive.
positive x positive = positive negative x negative = positive positive x negative = negative negative x positive = negative The same rules apply for dividing, since dividing is actually multiplying by the reciprical.
A test coming out positive means that the test found whatever it was looking for. A test coming out negative means it didn't find anything. Like a pregnancy test coming out positive means a good chance of the person tested being pregnant. Negative means there are no signs of pregnancy in the tested substance.
The same as the positive ones with negative signs.
Positive x negative = negative (Negative x positive = negative) Positive x positive = positive Negative x negative = positive So if the signs are the same the answer is positive and if they are different it is negative.
