 Vedic mathematics Multiplication by 11 Hi friends,   Today's topic is multiplying a two digit number with 11 in fraction of seconds.  Consider xy as a number     Xy ×11 The answer will be a three digit number.  The first digit is  x The second digit is (x+y) The third digit is y For example,  13×11=143 Here 4 is the sum of x and y Another example which involves carry 48×11 Solution: The last digit is for sure 8 The middle digit is the sum of 4 and 8 which is 12 Therefore, 2 is the middle digit of the answer and the 1 (in 12) is carried to the first digit.  The first digit is already 4  and now 1 is carried forward. Thus the first digit becomes 5(4+1)  The final answer is 528 This can be done in few seconds with more practice. This can  save time in your calculation.  We can see more tricks in our next blogs.  Thank you
Some tech facts: Wi-Fi (wireless fidility) is dangerous to health .It affects the brain and causes brain tumour. So  scientists have found a technology called Li-Fi(light fidility).It  gives the same facility with the help of light. New contact lens have come which also measures glucose level in the eye.I do not know more about this.
Let's learn some grammar! ADVERBS An adverb is a word which modifies the meaning of a verb,an adjective or another adverb. e.g. The cheetah runs quickly. TYPES OF ADVERB: Adverbs of time:  I did my work yesterday. Adverbs of frequency:  He often comes here. Adverbs of place:  God is omnipresent. Adverbs of degree:  Haj is too careless. Adverbs of manner:  The child slept silently. Adverbs of reason:   He therefore left school. Interrogative adverbs:   Where is your house? Adverbs of Affirmation and negation:  I do not know. Relative adverbs:   When I  went to the market ,I saw him.
VEDIC MATHEMATICS Some few math sums, Add 47*43 there is a trick in this. i.e.If  the second DIGIT'S sum is 10 AND THE FIRST DIGITS are SAME,then multiply 7 and 3 and also multiply 4 and the NEXT NUMBER(5)i.e.4*5 =20 7*3=21 THE ANSWER IS 2021 You can check this!
THE SUN The sun is a star and is a massive ball of burning gas.Without the sun, our planet would BE LIFELESS. The sun was born 5 billion years ago.75% of sun is hydrogen and the rest is helium.The sun's gravity is so massive that it pulls gas at the center pushes outside.This balancing gives the sun its ball shape.One should never see the sun directly.It emits dangerous radiation that can damage our eyes.The CORONA is the outer surface of the sun which can be seen during a solar eclipse.The hot spots of the sun are known as FACULAE.It takes EIGHT MINUTES for the sun's light to reach earth.
