Geeks on Mathematics.🤯💪

Hello guys, this is Herbert. Well, for some days, i realized i wasnt posting Educational matters here but today💪💪, i will be posting some nice shortcuts and other maths concepts which can help boost your speed and confidence in maths. "Geeks on mathematics" is going to be a new initiative by me coming soon. In that group, we will be solving maths and science questions and share ideas too.✌️🤗

1. Sum of (n) natural number;

=n(n+1)/2 .....eg.

Find the sum of the first 5 natural numbers.....

=5(6)/2=15.

Lets try it normally and see whether we will get this or not.

1+2+3+4+5=15✌️💪💪. Its right.🤗🤗🤗. Now let us go to the second one.

1. Sum of n odd and even number.

The formula for (n) odd number is;

n² or n x n. Lets find the sum of the first 5 odd numbers.

5²=25. Wow, this was damn fast right.💪. Okay lets use the counting method.

1+3+5+7+9=25 😍😍. Maths made so easy😁😁😁.

Now lets go to the even numbers.

The formula is n(n+1) .

Eg. Find the sum of the first 10 even numbers. Without counting the numbers you can solve it within 2 seconds😍😍👍💪.

10(10+1) = 110. Cool right. This is very fast. Now lets use normal method.

2+4+6+8+10+12+14+16+18+20= 110💘.

In my next article, i will be writing about;

• The sum of the square of the first n natural numbers.

• Sum of squares of the first n odd and even numbers.

I hope you liked this article. Please dont forget to suscribe to me for more and also give me a thumbs up too🤗🤗. # Maths made easy

Be inspired.🌻🌻.
