Is 1 x7 positive or negative
padilas [110]

Not sure if I quite understand your question. But ill assume that you're asking if 1 times 7 is positive. Or if 1x7 is positive.

1 times 7 equals 7 so it is a positive integer.

1x7 can be positive or negative depending on what x equals. If x is a negative number then the whole expression is negative. If x is postive the expression is positive.
