How do you know when a negative number is a negative or needs to be subracted in equations

I will try my best, but if this answer is incorrect you will have to elaboarate a little more. Check explanation.

Step-by-step explanation: 1. A negative number using the minus sign right next to the number to show it is negative. Negative numbers are less than 0. 2. I don't understand what you mean, could you please clarify?

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

it has the same slope and a different y-intercept

hope this : )
