Natural numbers are sometimes defined to include zero, sometimes not. Equivalent terms therefore may include: positive integers, non-negative integers, whole numbers, positive whole numbers ("whole number" is ambiguous; some take it to include negative numbers, some not).
If you add a positive and a negative number, the result can be positive, negative, or zero - depending on which of the numbers has the greater absolute value. Here are some examples: 4 + (-4) = 0 (zero) 4 + (-6) = -2 (negative) 4 + (-2) = 2 (positive)
Oh, dude, integers less than negative 3 include negative 4, negative 5, negative 6, and so on. It's like a never-ending parade of negative numbers marching further away from zero. So, if you're looking for some company in the negative realm, there are plenty of integers to keep you company below negative 3.
A negative number times a negative number gives you a POSITIVE number, not a negative number.
Its like reversing the procedure of minus. For example, in -(-1) , you are actually inverting the minus sign with the minus sign outside the bracket to become a positive 1. So in general, -(-x) is equal to x. well every time you see negative x negative gives you a positive. and a negative time a positive makes it negative. here are some examples: (-) (-)= (+), (-) (+)= (-)
