Explaining 1÷0, 0÷1 and 0÷0 To school stds

🎈🎈🎈🎈🎈🎈

Division is seen as repeated subtractions

For instance

20÷2

Can be seen as continuous subtraction of 2 frm 20 until 20 is exhausted.

The answer is 10 cos this can be done 10 times

What abt 1÷ 0?

Or any number (apart from zero) ÷ 0

it Is a continuous subtraction of zero frm 1(or de numba) till it is exhausted.

It can be seen in this case that, the subtraction can be done many billion times but it will not be exhausted.

Dats why any numba (except zero) ÷ by 0 is undefined or better still infinity

0÷1

How many times can one be subtracted frm zero?

Is zero times

Then 0÷0

zero is null, No value, or nothing

Hence the value of 0÷ 0 cannot be determine. Henceforth 0÷0 is known as 'INDETERMINATE'

WHY ZERO FACTORIAL IS ONE

0! = 1 for reasons that are similar to why

x^0 = 1. Both are defined that way.

You cannot reason that x^0 = 1 by thinking of the meaning of powers as

"repeated multiplications" because you cannot multiply x zero times.

Similarly, you cannot reason out 0! just in terms of the meaning of

factorial because you cannot multiply all the numbers from zero down

to 1 to get 1.

x^0 = 1 in order to make the laws of exponents

work even when the exponents can no longer be thought of as repeated

multiplication. For example, (x^3)(x^5) = x^8 because you can add

exponents. In the same way (x^0)(x^2) should be equal to x^2 by

adding exponents. But that means that x^0 must be 1 because when you

multiply x^2 by it, the result is still x^2. Only x^0 = 1 makes sense

here.

In the same way, when thinking about combinations we can derive a

formula for "the number of ways of choosing k things from a collection

of n things." The formula to count out such problems is n!/k!(n-k)!.

For example, the number of handshakes that occur when everybody in a

group of hakes hands can be computed using n = 5 (five

people) and k = 2 (2 people per handshake) in this formula. (So the

answer is 5!/(2! 3!) = 10).

Now suppose that there are 2 people and "everybody shakes hands with

everybody else." Obviously there is only one handshake. But what

happens if we put n = 2 (2 people) and k = 2 (2 people per handshake)

in the formula? We get 2! / (2! 0!). This is 2/(2 x), where x is the

value of 0!. The fraction reduces to 1/x, which must equal 1 since

there is only 1 handshake. The only value of 0! that makes sense here

is 0! = 1.
