Operational amplifiers (op amps) have 2 inputs that determine the output voltage.

LM358:

Noninverting input (+) voltage higher than inverting input (-) voltage = High output.

Noninverting input (+) voltage lower than inverting input (-) = Low output

High output means the voltage is as close to the positive supply voltage as it can get. A low output means the output is as close to the negative supply voltage as it can get.
