Question

What does prime and negative numbers mean.

Answer 1

There are several groups of numbers
natural number are counting number,,1,2,3,4,5,6..
whole numbers include 0 as well
integers means negative and positive numbers not including decimals =-6,-5,-4,-3,-2,-1,0,1,2,3,4,5...
so prime number is a number that cannot be factored out using integers. basically a number that the only factors are 1 and itself exg
3 is prime becuase 3=3 times 1
4 is not prime becuase 2 times 2 is 4
7 is prime becuase the only factors are 1 and 7



negative numbers are numbers less than zero
a negative number is like -1,-2,-3,-4,-5,-6,-7,-8,-9,-10...
when added, it's like subtraction exg
add 3 and -2 together=3+(-2)=3-2=1

Answer 2

Alright so lets start with prime numbers.
A prime number is a number that can only be divided evenly by 1 and itself. For example, 7 is a prime number it can only be divided by itself and 1, if it's divided by anything other than 1 and itself, the answer will be a decimal number. 4 is not a prime, because it can be divided by 2.

Now onto negative numbers.
Normal numbers exist on a line, starting with 0, all numbers to the left of it are positive, like 1, 2, 3, 4,... , but to the right of zero are the negative numbers ...-4, -3, -2, -1. Negative numbers are the opposite of positive numbers, so that means the larger the number looks, the smaller the quantity is, so -20 is actually smaller than -10. Think of it like this, would you rather owe someone 20 dollars or 10 dollars? A number line with positive and negative numbers would look like 
.....-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5,........
Notice how the negative numbers count down from left to right, this is because the greater numbers on the number line are to the right and as I said before, the smaller a negative looks, the greater it actually is.
I hope all that helped.
