Which of the following represent positive numbers?

I. −3 − (−5) 
II. (− 3)(−5) 
III. −5 − (−3)

A. I only 
B. II only 
C. III only
D. I and II 
E. II and III

Solution:

To determine which expression is positive, we analyze Roman numerals, I, II, and III.

I. −3 − (−5)

−3 − (−5) = - 3 + 5 = 2

I is positive.

II. (− 3)(−5)

(− 3)(−5) = 15

II is positive.

III. −5 − (−3)

−5 − (−3) = -5 + 3 = -2

III is NOT positive.

Thus, Roman numerals I and II are positive.

III. −5 − (−3) = -5 + 3 = -2

Option D(I and II)  are the positive numbers.

HasnainAfxal · Answer

1) -3+5=+2
2) (-3)(-5)=+15
3) -5+3=-2

Answer D

sunngupt11 · Answer

Note: Multiplication of two negative number is positive. 
I. −3 − (−5) = 2 (positive)
II. (− 3)(−5) = 15 (positive) 
III. −5 − (−3) = -2 (negative)

From above we can see that I and II both are positive.

answer: D

TheNightKing · Answer

I. −3 − (−5) = 2 (positive)
II. (− 3)(−5) = 15 (positive)
III. −5 − (−3) = -2 (negative)

Hence D.

ManifestDreamMBA · Answer

I. −3 − (−5) = -3 + 5 = 2, eliminate B, C and E
II. (− 3)(−5) = 15 D is the answer, no need to calculate III
III. −5 − (−3)

totaltestprepNick · Answer

I) -3 - (-5) --> -3 + 5 --> 2

So, Roman numeral I is a positive number, which means we can eliminate answer choices that don't contain I, which means we get rid of B, C, and E. Since the remaining answer choice D doesn't contain Roman numeral III, we don't have to check it, and therefore only check Roman numeral II next:

II) (-3)(-5) --> 15

Since Roman numeral II is also a positive number, the answer is D.

AbhishekP220108 · Answer

Apply the number property 
In 1 -ve×-ve=+ve and also magnitude of 5 is bigger and sign chances to positive after opening the bracket,hence positive.

In 2 -ve×-ve=+ve

In 3 -ve×-ve=+ve sign chances to positive after opening the bracket,however the magnitude of 5 is bigger than 3,hence negative.
