Which number sentence is always true? Select all that apply!

Positive - positive = positive
Negative - positive = negative
Negative + negative = negative
Negative + positive = positive
Positive + positive = positive
Positive - negative = negative

Step-by-step explanation:

Negative - Positive = negative    TRUE

eg:   -5 - 2 = -7

Negative + Negative = negative   TRUE

-8 + ( -2) = -10

Positive + positive = positive      TRUE

8 + 2 = 10

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted
