If you're looking at a math problem or textbook - it is probably theta - usually used for denoting degrees in an angle
or the null set - a set with nothing in it. (slant is usually a forward slash, tho)

Actually, it means neither zero nor theta. A sideways slash ( like this: / ) should not be confused with a horizontal slash (like this: - ) The "O" with a horizontal slash is in fact the Greek letter "theta" and is used to represent the measure of a given angle in mathematics. The "O" with a sideways slash is in fact the Greek letter "phi" and is used in several ways in mathematics; at times, it is even used to represent a second given angle measure if theta has already been used.
On the other hand, "phi" is also used to represent a type of nothingness (stay with me here) which is different from zero. If the answer to a question is "Does not exist", then you could use this phi symbol to represent that. However, "Does not exist" and "zero" are very different answers and should not be confused. For your sake, I would encourage you to keep in mind that the "phi" symbol (with the sideways slash) is not the same as the "theta" symbol (with the horizontal slash) and is also not the same as zero.

It simply means the number zero. They put the slash through it to make sure it's not taken as the letter (variable) O.

1. it s called Theta used to mention the degree
one more symbol used to mention the diameter that is fie
2. If you're looking at a math problem or textbook - it is probably theta - usually used for denoting degrees in an angle

It is to show 'zero' . Usually used to when there are '0' 's as in the letter.

It's zero & the slash is for it not to be mistaken with alphabet's letter "O".

It's probably a phi, which stands for the empty set, the set with nothing in it.
