This needs to be studied 😅

E get how you go Dey jobless reach you go just Dey thinking waiting you no need to think about at all

Lol Make I shock you I have used the same number before in different countries but the difference is the area code of the countries

This no sabi Wetin be permutation

It's an endless series of permutations that are never the same

When a user die his phone is giving to another user, more like when it isn't action for a long time it become dormant and enter the list of number pool to give out that's when the mobile network distribute it and allocate the previous deceased number to a new user.

This so naive. lol Someone tell her about E.164 standard. The pool is still enormous despite all the practical constraints.

It’s maths. One of the reasons why school is not a scam.

Have you never heard of permutation?

Permutation and combination for maths that years Abi?

i can search the numbering system. apparently one number per human was too merciful

That’s where the + (area code)comes in.

Make I waste my time the think dis kind thing?

she no do math for school sequence and series

Smh @grok explain to them

Some have multiple numbers

Them don kill am for comments section 😂😂😂

I’m ashamed to see what is bursting her brain 💔, simple combination and permutation o

News flash, someone can share the same account number with you, even more than 3 people

Olodo it’s permutation. And there’s someone with my phone number but different dial code. 07026855598 Nigeria +447026855498 Uk.

Sounds dull

We can a d same act number wit different serial num

At last, school no be scam

It is called programming my sister Computer science student go do laugh tired 😅

Permutations! This is taught is Secondary School.

Area code madam. Why are women dull.😭

The combination of 11 digit numbers between (0 - 9) has about 100billion possible outcomes. The world’s population is just about 8 billion. The telecom regulators’ systems then have a kind of validation that prevents the same number being assigned to different users.

My IQ bro God I apologize for the 50secs of my life I wasted I’m sorry

This girls brain ehn Na God know wetin him put inside

Omo you wan stress my brain again 😒
