First of all, the circle on -3 did not have filling so that means it is not equal to z. Then we look on the circle on 6. It does have a filling which means it is equal to and greater than z. Now we look in between -3 and 6. Is there any white spots? If no, then we don’t have to use an OR. Therefore, the first answer is the only plausible answer.
Becuase 80 is the same as 8 but has an extra 0 at the end (which makes it 80) and same for 20 to 2. 8 + 2 = 10 (now add a zero at the end). The answer should be 100.
