If x equals a negative number, what is the additive inverse of the number -x? Explain. How do you add a positive number and a negative number? Give a numerical example when negative + negative = positive. If a negative number is multiplied by a positive number, is it possible to get ...

This last “proof” though is unlikely to justify that a negative times a negative is a positive for any students though. It’s the kind of thing which is a required level of justification for a mathematician interested in rigorous proof who would likely consider the other justifications “patt...
If the number was originally positive, it becomes negative and if the number was originally negative, it becomes positive.Answer and Explanation: When a positive number is divided by a negative number, the quotient has a negative sign. Suppose we divide 4 by −2. Ideally,.....

For the path from social skills to evidence sharing, we again found one statistically significant positive coefficient, but in the other two studies it was < 0.1. Therefore, we do not consider Hypothesis 3b to be supported by the data. The same applies to the path from social skills to ...
a negative property if only a single optimization attempt is performed since it makes required iteration budget unpredictable. But if several attempts are performed, it is a positive property: it means that in some optimization attempts BiteOpt converges faster and may find a better optimum with ...
If it is the case that one variable has a negative correlation with all the other variables, these correlations can be turned to positive by reversing the order of categories for the variable. That is, if the variable in question, \(Y_j\) say, may take the values \(0,1,\ldots ,q...
