explanation:
Yes: Negative numbers are less than zero. No: Zero represents 0-dimensional —a vertex where lines intersect. Positive and negative numbers are directed numbers, in reference to zero, which is neither positive or negative. Zero in reference to itself is zero dimensional —other numbers represent a one-dimensional directed line segment on ... Actually, there is much more than “a number” less than zero - there are an infinite number of them. Most middle school aged students (around 8th grade in the US, perhaps earlier if you’re in accelerated math) learn about the concept of NEGATIVE NUMBERS. “Integers” is the precise term for positive and negative whole numbers (e.g. 4, 3, 2, 1, 0, -1, -2, -3, -4, …), but you can also have negative decimal numbers too, such as -3.42314.
