• Is zero considered positive or negative?
Some college people say it's positive,yet my teachers say it's "neutral."
• Zero neither positive or negative. For once, college students are wrong in something they are good at!
• Is anyone here finding this stuff way too easy, and is in a lower grade than 7? This is too easy.
• Even if it is easy it still helps to build your skills
• -4=_-9.(the example)

isn't -13-9 =-4 or am i wrong
• You have it backwards! It's 9-13 not 13-9.
• When you do problems like this, I like to do something called cha-ching. This basically is when you flip the symbols. Here's what I mean. 2-(-4) becomes 2+4. There you flipped the subtraction sign and the negative sign. Make sure to upvote this
• does anyone else get SUPER confused on this or what?
• The more you decide to practice the better you will become and the easier it will be.

• Is zero considered positive or negative?

• Zero is neutral, neither positive nor negative.
All positive values are values greater than zero, and all negative values are values less than zero.
