what do they mean?

Write an inequality to show "a number,b, is positive" ?

b>0 Does that do it?

if b>45, b is also positive

if b>343, b is also positive.

inequality means????

To write an inequality that represents "a number, b, is positive," we can use the symbol ">" (greater than). The inequality would be:

b > 0

This inequality states that "b" is greater than 0, which indicates that "b" is a positive number.

To understand why this inequality represents a positive number, let's break it down:

- The symbol ">" means "greater than."
- The number 0 on the right side represents the reference point. Any number greater than 0 will be considered positive.

Therefore, if "b" is greater than 0, it means that "b" is a positive number.
