What is a signed number?

1 answer:

6 0

A signed number is a number with either a + or - in front of it. this doesn't mean that you are adding or subtracting it though. a negative number is a signed number. a positive or whole number is a signed number, but we don't usually write the + sign in front of it

hope this helped :)
