REALLY Fast & Accurate Multiplication!!!(Vedic math)

Multiplication- as it should be done (Vedic math)                   


Ever been thwarted by a math exam because of your slow or inaccurate multiplication, even when u know your trigonometry ratios. Here’s a method to uncomplicate your life and save you the invaluable time in your math exam

Principle:

This method mainly states multiply diagonally wherever possible and if not, multiply vertically

Brief history (as if you wanna know😏!):

This method was obtained from the Sanskrit Vedas, and therefore is considered a part of Vedic math but you don’t want me babbling about its history, so here is the method… 


Lengthy Tutorial:

1)      You would first want to take out a piece of paper 😛
Ok fine, I get it… for real now
1)      For this example, we’re going to multiply 141 and 132


2)      Then we’re going to consider the leftmost digit of both the numbers and multiply them. In this case 1x1. Write the product i.e. 1, underneath. Like this:



3)      Next, we take the 2 leftmost digits of both the numbers and multiply them diagonally, add both the products and write it alongside 1
4)      Now we consider all the digits, multiply the extremes diagonally, and multiply the middle digits vertically, and add all 3 products. As the sum is 15 we write the 1 subscripted to the 7 and the 5 underneath.
5)      Now we consider the digits at the ones and the tens unit of both the numbers and multiply them diagonally and do the usual (you must’ve got the hang of it by now).

6)      Now we consider the rightmost digits and multiply them vertically


7)      Now you got to add the carry overs. And voila!! You got your answer. Simple, right?
Same principle for a different number of digits… multiply diagonally whenever possible and vertically when not possible. This method also has another benefit. It gives you the most valued digit first, which can help you estimate and works a wonder in competitive exams!

Some words of caution:-

·        Take care of the place values. Tens should be under tens, hundreds under hundreds,
·        Make sure you add the products. Not multiply them.
you find it tedious to calculate the square root of numbers? Think its too long of a method? Here's something that might help!!!
This is my first article here, hope you guys like it. Comment below for help or what you wanna see me write next. Reviews are highly appreciated. Stay tuned for more awesome work from me…

Have a nice day showing off your super mathematical powers to your friends

Android Versions Named After Sweet

Have you ever thought why are Android versions always named after sweet names ?? Everytime a new Android version is launched its name is kept after a sweet name. Many people have researched about this topic and many have asked Google also. Have you ever tried to find out the core reason behind this? If not then you would find the answer here . First of all let us first see what Google says about this : In 2008 i.e. the year when Android was launched a reporter asked the reason for the same. At that time Google said “It’s kind of like an internal team thing, and we prefer to be a little bit — how should I say — a bit inscrutable in the matter, I’ll say,” said Randall Sarafa, a Google spokesman. “The obvious thing is that, yeah, the Android platform releases, they go by dessert names and by alphabetical order for the most part."

2-D & 3-D GEOMETRY

2-D & 3-D GEOMETRY We all have some amount of geometry. We know that any line can be represented on the Cartesian plane. Any figure can be drawn on it. But can we represent a 3-d object on it. Yes we can. A Cartesian plane has 2 axis. While representing in 3-D we need to add a third axis. This axis does not come in between the axis or in the same plane. It appears to be coming out of the paper as we cannot represent a 3-d object on a 2-d surface. This new z-axis represents a line coming out of the screen. Before understanding 3-d geometry you need to imagine this axis coming out of the screen.  REMEMBER : all the three axis are perpendicular .i.e there an angle 0f 90 between them and they meet at the origin If you are unable to imagine you can take a thick book as an example. Any corner becomes it origin and the three edges as the three axis REPRESENTING 3-D GEOMETRY Like in 2-d geometry we represent the value of the different axis as (x,y) we use the sa...

Animal and Plant Cells

 Cells Cells are the basic functional, biological and structural unit of life. The word cell is a Latin word meaning ‘small room’. Cells are also known as building blocks of life.  The branch of science that deals with the form, structure, and composition of a cell is known as Cytology. All organisms around us are made up of cells. Bacteria, ameba, paramecium, algae, fungi, plants and animals are made up of cells.  Cells together form tissues. And tissue together makes an organ. History Of Cell The cell was discovered by Robert Hooke in 1665. He assembled a simple microscope and observed a very thin slice of cork under his primitive microscope. The cork was obtained from the outer covering of a tree called bark. Robert Hooke observed many little-partitioned boxes or compartments in the cork slice. These boxes appeared like a honey-comb. He termed these boxes as the cell. He also noticed that one box was separated from another by a wa...

The Inverse & Reciprocal TRIGONOMETRIC Functions

So, this is my second post on trigonometry. In this post we're gonna cover the reciprocal and the inverse Trigonometric functions. If you haven't seen my first post you should definitely view it as it covers the basics of Trigonometry The Reciprocal Trigonometric Functions The reciprocal Trigonometric function of Sine is Cosecant, of Cosine is Secant & for Tangent it is Cotangent. Cosecant (Csc θ = 1/Sin θ) or (Hypotenuse/Opposite) Secant (Sec θ = 1/Cos θ) or (Hypotenuse/Adjacent) Cotangent (Cot θ = 1/Tan θ) or (Adjacent/Opposite) We can also represent Tan θ in another way. As Tan θ = opposite/adjacent  & Sin θ = opposite/hypotenuse  & Cos θ = adjacent/hypotenuse ∴ Tan θ = Sin θ/Cos θ (The hypotenuses cancel out) As Cot θ = 1/Tan θ  So, we can also represent Cot θ as Cos θ/Sin θ.

Finding Square Roots Easily (Vedic Math)

Finding Square Roots Easily (Vedic Math) Hello, Guys!!! I’m back with another post on Vedic Math that is going to keep you glued rooted to your spot 😆. This time I’m going to teach you how to calculate the square roots of perfect squares faster… With a little practice, this method can let you calculate the roots in a matter of 5 seconds, whereas if you had used the traditional method, you would still be stuck with your question 😏 Things you need to know:- Perfect square which has unit digit 1 will have square root with the last digit as 1 or 9 Perfect square which has unit digit 4 will have square root with the last digit as 2 or 8 Perfect square which has unit digit 5 will have square root with the last digit as 5 Perfect square which has unit digit 6 will have square root with the last digit as 4 or 6 Perfect square which has unit digit 9 will have square root with the last digit as 3 or 7 Perfect square which has unit digit 0 will have square r...
