Does anyone know what the sign that looks like a circle with a line going across means?

This depends on how the line is going across. If the line is horizontal and divides the circle in half, then the symbol is a 'theta', which usually stands for an angle. If it is from lower left to upper right and extends beyond the circle both ways, then it could be the symbol for the empty set or (in some books) zero. If it is close to vertical and extends beyond the circle in both ways, then it is a 'phi' and again usually represents an angle.

The position of the arrow and the cross on the circle helps explain their meaning. The symbol for female (Venus) is a circle placed above a cross, while the symbol for male (Mars) is a circle with an arrow pointing upwards (to the right).\n\nA cross with a circle at the top represents the rise of spirit over matter. Considered a feminine quality, this represents female energy.\n\nA circle with an arrow pointing upward indicates matter in supremacy over spirit. Considered a masculine quality, this represents male energy.

The reason for the line in the numeral zero is the circle with a line through it is the Greek PHI.  This is the symbol used to represent the Null set (a set containing nothing or containing zero members).  It is used (or has been used) to help differentiate the written zero from the letter Oh.

Your best bet would be to just ask your mom, like someone has already mentioned, but you could also look at symbols.com  It has listings of all sorts of western symbols and their meanings.  I've included a link to one symbol that looks like it may be what you're looking for.  If so, it's probably a protective symbol.

It's Pentacle and Triquetra.\n\nThe pentacle has many meanings, but the most basic is the elements. Earth, Air, Fire, Water and spirit. These are the five points. The circle around it represents the circle of life and death, the seasons, etc.\n\nThe Triquetra is a Celtic symbol, representing triads, such as Maiden, Mother and Crone, which are the three stages of a woman's life. It also represents the moon, Waxing, full, and waning, which represent the stages of the Goddess. The Triquetra was popularized by the TV series Charmed.\n\nPagan symbology is very rich, and it's nigh impossible to talk about all of it in even a single volume. Below are a couple sites to get you started.
