Put This Video on Your Myspace or Blog: Put This Video on Your Myspace or Blog:The following tips are taken from the book "Rapid Math Tricks and Tips" (c) 1992 by Edward H. Julius. The tips themselves are public domain and the author's direct explanation or examples are not used. This is not the full list of tricks. Mistakes listed here do not reflect the author of the book.
Simply double the number twice and adjust the decimal, because 2x2=4
Double it three times, because 8 is 2 x 2 x 2
Divide by two and adjust decimals, because 5=10/2
Multiply the tens digit by a whole number, then attach 25 to the end.
Add the two digits your multiplying by 11 together and put their sum in the middle of the same two digits. 12*11=?, 1+2=3,solution 132
Divide by four, and adjust the decimal. Because 2.5=10/4.
Multiply times 4 and adjust the decimal.
Substract the number by one and call it value 1, then substract the number from 100 and call it value 2. Put the two values together.
Write the number twice and adjust the decimal. 64*101=6464
Divide by 8, adjust decimals. Because 5/4 or (10/8) is 1.25.
Multiply 8, adjust decimals. Because 5/4 or (10/8) is 1.25.
Multiply the value your multiplying times nine, time 10 instead. Take that solution and substract the value your multiplying times nine from it. 9 x 21, we say 10 x 21 =210-21=answer.
Multiply times 10 and call it value 1, multiply times 2 and call it value 2. Add the solutions. 12 * 60= (10x60)600+(60*2)120
Multiply by 10 and get value 1, divide by 2 then multiply by 10 and get value two. 15*34 = (10x34)340+((34/2)*10)170
