2What is vadic maths?Vedic mathematics is the name given to the ancient system of mathematicsIt’s a unique technique of calculations based on simple principles and rules , with which any mathematical problem - be it arithmetic, algebra, geometry or trigonometry can be solved mentally
3Instant calculations: All from 9 and the last from 10 to perform substractions.e.g =543VERTICALLY AND CROSSWISE you don’t need to the multiplication tables beyond 5x5.e.g. 8x7;7x6;
4Instant calculations: VERTICALLY AND CROSSWISE to write the answer straight down!e.g.Multiply crosswise & add to get the numerator, & multiply the denominators to get the denominator.
5Instant calculations: Quick way to square numbers that end 5 =>BY ONE MORE THAN THE ONE BEFORE.e.g.i)The first number (7)multiplied by the number”one more”,which is 8;ii)Is always25;
6Instant calculations: Method for multiplying numbers where the first figures are the same and the last figures add up to 10.e.g.i)We multiply 3x4=12;ii)We multiply the last figures;
7Instant calculations: Multiplying a number by 11.e.g.26 x 11=286;77x11=847;i)we put the total of the 2-figures between the 2-figures;Method for diving by 9.e.g.43/9=4;232/9=25,(r.2+3+2=7)i)The first figure of 43 is 4=>the answerii)Reminder 43=>4+3=7
8Multiplaying by 12-shortcut e.g. 12 X17;i)We multiply the 1(of12)by the number we’re multiplaing =>1x17=17;ii)Then => 17x10=170;iii)Multiply the 2x17=34;iv)Add =204;
9Is it dividible by 4?For 4 to divide into any number we have to make sure that the last number is even;e.g.1234/4=?i) 4+(2x3)=10 =>4 goes into 10,two times with a reminder 2,doesn’t go in evenly;but, /4=?i) 6+(2x5)=16,&4 goes in 16 evenly;
10Adding time A simple way to add hours and minutes together: Let's add 1 hr and 35 minutes and 3 hr 55 minutes together.i) =490ii) No matter what the hours and minutes are,just add the 40 time constant to the sub total.=>490+40=530 (finaly 5h.30min)
11Kilos to pounds How to convert Kilos to Pounds, & Vice Versa? Converting Kilos to pounds:e.g.86 kilos into pounds:i)Multiply the kilos by 2;=>86x2=172;ii)Divide the answer by 10;172/10=17,2;iii) i)+ii)=189,2;=>86kilos=189,2pounds
12Temperature conversions This is a shortcut to convert Fahrenheit to Celsius and Vice Versa;e.g.74°F=?°C74F-30=44;ii)44/2=22 °C;74 Fahrenheit=22Celsius
13Converting Kilometres to Miles Useful method for when travelling & need to know what kilometres to miles are;Formula=> number of (km / 8 ) X 5e.g.80 km into miles;=>(80/8)x5=50 miles
14To sum up:Vedic Mathematics is becoming popular all over the world due to the following: * It helps a person to solve problems times faster. * It reduces burden (Need to learn tables up to nine only) * It provides one line answer. * It is a magical tool to reduce scratch work and finger counting. * It increases concentration. * Time saved can be used to answer more questions.
