The square of any prime number is a semiprime.

Factorization

Generating prime numbers

Let's start by dividing all numbers into two categories.

Ben Any number.

I get to 42. Well, the prime numbers.

2 is interesting, because it is the only even prime number.

2539 is a prime number.

Number of elements to permutate

So the real part is a, the imaginary part is bi.

Prime, not prime. Not prime.

And so we only give you prime numbers

In future videos I'll actually do examples where we'll make more use of complex numbers.

And finally the len operator that takes a list as its input and produces an output number that is the length of the list.

Or sometimes someone will write,

And our vertical axis is going to be the imaginary part.

Number of elements to choose

Our current well, we don't have one either.

What about 51? Is 51 prime?

2x minus 3 times x plus b. b is minus 1.

So it has only 2 factors, 1 and itself.

Or we could write that as if we wanted to write that in the traditional complex form is eight thirteen plus one over thirteeni.

It's not in the set of reals that's a complex number.

So what is 20u squared v if we factor it out?

Finally, we zoom out to see millions of numbers.

That's pretty much every number outside of the complex numbers.

Move the orange dot to 2 2i.

So when you add these two complex numbers you get 8 5i.

That's interesting.

And just as a little review.

In this case 2, 3, and 5 are the prime factors of 30.

And just as a refresher, a prime number is a number that's only divisible by itself and one, so examples of prime numbers let me write some numbers down.

And by definition, these smallest numbers are always prime numbers.

Can we take a square root of a negative number?

And so 8 is clearly a member of the real.

The group's elements are variables

The group's elements are functions

Add prime factor 2.
