Squaring<\/strong>
\nIn this simple trick we need to modify the equation and make the units digit zero. After all it is easy to multiply when units digit is zero.<\/p>\n

For example – Find square of 43
\n= (43+3) \u00d7 (43-3) + (3\u00d73)
\n=(46\u00d740) + 9
\n= (460\u00d74) + 9
\n= 1840 + 9 = 1849<\/p>\n

Multiplication<\/strong>
\nVedic maths gave us the easiest method to do complex multiplications quickly. This method can be quickly explained with an example.<\/p>\n

Multiplication with 5
\nSimply multiply the number by 10 and then divide it by 2.
\nFor example 99\u00d75= 990\/2= 495<\/p>\n

Multiplication with 4
\nMultiplication with 9
\nMultiplication with 6<\/p>\n

Mixture<\/strong>
\nQuestions related to mixtures can be easily solved by alligation method. By using alligation we can wide arrange of maths questions. Let me explain this with a simple example<\/p>\n

Example<\/strong><\/p>\n

Price of wine of $60 per liter. If Samuel is adding water with and selling the mixture for $40 per liter. Profit margin remains same. What is the ratio of water and wine in the mixture.<\/p>\n
