-a > 0
how can that be?
u can put another negative in the a spot
like --2>0 because a double negative equals a positive
thanks
The expression "a > 0" represents a comparison between the variable "a" and zero. "a > 0" means that the value of "a" is greater than zero. So, the inequality "a > 0" can be read as "a is positive".
To understand why and how this can be true, let's break it down step by step:
1. Start with the given inequality: a > 0.
Here, "a" is a variable representing an unknown value.
The ">" symbol signifies "greater than".
2. To determine if the inequality is true or false, you need to consider different scenarios for the value of "a".
a) If "a" is a positive number (greater than zero), then the inequality is true.
b) If "a" is zero, then the inequality is false since "0" is not greater than zero.
c) If "a" is a negative number (less than zero), then the inequality is false since no negative number is greater than zero.
3. Thus, the inequality "a > 0" is true when "a" is a positive number.
To summarize, the inequality "a > 0" expresses that "a" is a positive number.
