Why do our mobile numbers have 10 or 11 digits?

Why not five? After all, a number with five digits is an easy number to remember.

Let us assume that a country’s government decided to introduce a law that only allowed five-digit mobile numbers.

Most countries have over a million people living in them. Each person having a cell phone means that many people may get the same number.

How does this work?

In a population of a million people, there are only 1,00,000 ways in which a five-number having digits 0 to 9 can be combined. There won’t be enough numbers to assign to so many people.

10-digit mobile numbers give a person 10 billion combinations, which is still more than all the people on earth.

So in case you want a new number, you needn’t worry.

Also, some countries use 11-digit mobile numbers. So you’ll never be worried about a cross-connection.

Stories of kindness always bring a smile to our faces. Let’s face it: all of us – irrespective of age, gender, political differences, or race have some kindness ingrained in us. While some of us attribute our acts of kindness to what our parents, teachers, and friends taught us, more recent research also states that kindness is learnt while learning mathematics.

While the claim seems baffling to some, there is a logical explanation. Let us talk about how we learnt fractions when we were children vis-à-vis how children learn it today. When we were in school, we were taught about numerators and denominators, and least common multiples. But today, with teaching techniques constantly evolving, fractions are taught in such a way that you learn other things as well.

Let me give you an example: You are given 3\4th of a cake, while your friend receives 1\4th of the cake. How much cake will you give your friend to ensure you have equal portions? If you said you will have to give 1\4th of your slice, well done! You got the math. However, the problem also teaches you the wonders of sharing. While mathematics does not directly explain the relationship between fractions and sharing, there is a subtle message that a child always picks up.

Kindness and adults

As adults, kindness is a more complex mathematical equation compared to fractions. I’d like to highlight exponents here and this can be explained through the acts of kindness that are being seen during the COVID-19 pandemic.

The pandemic, no doubt, has affected us directly or indirectly. However, a WhatsApp forward or a retweet calling for help is how a message can be sent exponentially.

Let’s give you another example here. Person A is in need of oxygen and puts out an SOS on Twitter. The message is retweeted by a follower, who has 1,000 followers. Of these 1,000 followers, one person with a million followers retweets it, and the message spreads far and wide, and within the next few hours, Person A has a tank of oxygen at home and is able to ensure that their loved one is safe.

While this has been the norm during the second wave, it also explains how it is exponentially possible to spread kindness – even if it is to help a random stranger. The beauty is that there are no expectations either.

Can kindness be taught?

Interestingly, people are also using the way they teach mathematics to teach kindness to children. Australian Kath Koschel, who established the Kindness Factory in 2015 to make the world a kinder place, in a blog titled ‘Why we should teach kindness like we teach maths’, said, “The Kindness Curriculum not only intends to seamlessly exist alongside the current Australian Curriculum, it seeks to play as much of a role in children’s development as other key educational subjects, like maths.”

Koschel has in fact developed a curriculum that is intended for K-10 learners. Now, if we could also explain mathematical concepts in that curriculum, then we have an absolute winner.

You aren’t born kind; kindness is taught. If we, both as parents and teachers explain the concept of kindness using mathematical examples, it can teach the child both empathy and logical reasoning. A combination of both makes the ideal problem solver.

When you learn Math visually you don't need to memorise. Cuemath method empowers children to learn math by reasoning and visualization instead of memorizing. Come discover the Cuemath method.

Math and logic go hand in hand. For some, it is just another manhole cover, but once you understand the logic behind its shape, you will realize why it is a mathematical marvel.
Come discover the Cuemath Method and learn more about the why behind the what of everything around us.

One of the basics of mathematics is knowing whether the number is even or odd, divisible by 2 and by the sum of its numbers .. But look at this strange number ..!
The number 2520》 looks like a normal number like other numbers, but it is not like that. It is a strange number and is rarely found between numbers and has puzzled mathematics geniuses to this day .. !!
The strange thing is that it is divisible by numbers from 1 to 10, whether these numbers are odd or even !!
It is known that it is difficult or even impossible to find a number that does that !!
And when we say the division is accepted, we mean without any fractions remaining after the division process ... !!

* Follow the practical application:

2520 ÷ 1 = 2520
2520 ÷ 2 = 1260
2520 ÷ 3 = 840
2520 ÷ 4 = 630
2520 ÷ 5 = 504
2520 ÷ 6 = 420
2520 ÷ 7 = 360
2520 ÷ 8 = 315
2520 ÷ 9 = 280
2520 ÷ 10 = 252

And after mathematicians were confused about finding a convincing mathematical relationship that would make one number divisible in this strange way, they discovered that this number is the product of the numbers: 《7 x 30 x 12》 that may appear at first glance to be random numbers, but it is not !!
So the surprise that made them more confused than their first was that this number 2520 is a multiplication:
Days of the week 7 x days of the month 30 x months of the year 12.
