A number n is positive: n > 0
Yes.
12 is greater than 8 Multiplying the inequality by any positive number leaves the inequality unchanged. In this case, the positive number is 1/4
You only need to reverse the order of the inequality when multiplying or dividing both sides by a negative number. If you multiply or divide by a positive number, the order of the inequality remains the same. This is crucial to maintain the truth of the inequality. Always be cautious about the sign of the number you are using in these operations.
Choose a nonzero integer for n to show -n can be evaluated as a positive number?
if p represents your positive number, and n represents all of your negative numbers, then: |∑n| < p

The whole point of using n in algebra is that it stands for an unspecified number. Until you have an equation (or inequality) that involves n and solve it for a value of n.
It is the inequality: N + 2 <= 1.

The inequality symbol doesn't change direction in this case.Note that that is the same as adding a positive number.Note also that if you MULTIPLY or DIVIDE by a negative number, then you need to change the direction of the inequality symbol.
if (n>0) printf ("%d is positive\n", n);
Sometimes.* If "n" is positive, "-n" is negative. * If "n" is negative, "-n" is positive. * If "n" is zero, "-n" is also zesro.
That would be -n. Note that if n is positive, -n is negative, whereas if n is negative, -n will be positive.
Negative number = -N , where 0 < N < ∞ . Positive number = +K , where 0 < K < ∞ .
if p represents your positive number, and n represents all of your negative numbers, then: |∑n| < p
