basically a positive is a blank thing that doesn't do anything while a negative makes change happen (opposite)
with 1 blank thing and an opposite, we get an oposite
so we havve -7 times +11
we can factor out the -1 in -7 so we get
-1 times 7 times 11
we know that 7 times 11=77
then the negative makes it oposite so -1
therefor
if you have -x times +z that equals -1 times (x times z) and since x and z are both positive, they remain so, but the -1 makes it negative
so this statement is always true
11 x -7=-77
negative times positive = negative
ALWAYS!

Given: in standard form.
The standard form are also known as scientific notation.
Scientific notation is a way to write a very large or a very small number in the product of a decimal form of number [generally between 1 and 10] and powers of ten.
Since the power of 10 is negative, then it must be smaller than 1.
We can write the given number in decimal form as

surprise, 1 is not prime because it must be divisible by itself and 1 and the factors of 1 are 1 and 1 so 1 is not prime
2 is prime because it is the first even counting number and since all even numbers after 2 are divisble by 2 you can cross out all odd numbers after 2
3 is prime because it is the first odd counting number that satisfies the condition
4 is not because it is even
5 is prime
6 is not because it is even
7 is prime
8 is not because it is even
9 is not
10 is not because it is even
11 is prime
12 is not because it is even
13 is prime
