Ill teach u a trick to check all addition and multiplication problems.ONLY addition and multiplication.
Eg Suppose you get 35*38=1280 then its wrong.How to check this without calculator??
Ans:
1.Add up digits of first number until you get a single digit.
Here 35=3+5=8.
2.Add up digits of second number until u get a single number.
Here 38=3+8=11=1+1=2.
3.Multiply the sum of digits of first and second number and add the digits until u get a single digit.
Here 8*2=16=1+6=7.
4.Check the answer by adding the digits of the product.
Here 1280=1+2+8+0=11=1+1=2.Since LHS=7 and RHS =2.Answer is wrong.
Correct answer is 1330=1+3+3+0=7.
Since LHS=7 and RHS=7.The answer is correct.
Same for addition except in the 3 step add the sums of the first number and the second number instead of multiplying.
Eg:37+78=115.Correct as 37=3+7=10=1+0=1 and 78=7+8=15=1+5=6.6+1=7.LHS=7. and RHS =115=1+1+5=7.

i'm the two good at the two Maths & English / English & Maths ! I do like to artwork with Figures fairly of the female style ! I have been given a GCE "O" point in the two English & records at Sackville finished college in East Grinstead in West Sussex ! you may no longer beat 36D-24-36 as a sequence of woman needed records in my own opinion !

very good!
you could buy a for some guy called "Tony Chaheen"
that teaches all the methods for fast mental calculations!
did you know that when you choose a best answer you get three pts!?

I doubt if it always works.
What is the Mathematical logic behind this

ya, quite interesting.
Are you sure it works for all the numbers and cases.

that's pretty cool :)
i hope i can remember how to do it though...because when i actually need to know this i'll probably have forgotten it already :S
anyways, thanks for sharing that trick :)
