Maths shorcuts

xa + yb + zc = 1 : this would be 1a+ 1b+ 1c = 1
How can you compute this if you don't have equivalents for variables a,b & c??


x+y+z/xa + x+y+z/yb + x+y+z/zc will be equal to ?
For this we simply put x = y = z = 1 and we get the answer as 3

How it become equal to 1??
what will be the value of a,b & c?? 1 Also??

You know what, you’re right. It is impossible to get an answer of 3 using his explanation, unless all of the variables will be equal to 1.

I have been staring at this like a 1st grader in a college class. It doesn't make any sense. x = y = z = 1 means everything is equal to one, but it's also somehow equal to three? Is this the new math I've been hearing so much about?

this is good one. I also want to share some more these are..

Multiply By 4


To quickly multiply by four, double the number and then double it again.
Often this can be done in your head.

Multiply By 5

To quickly multiply by 5, divide the number in two and then multiply it by 10. Often this can be done quickly in your head.

wooh... hehe,, i dont like math.

when i was studying in school i use to solve these equation very quickly but after ten years this equation puzzling me.

Math develop your grasp.

I know the formula,really interesting.

l.o.l. its really funny. Thanks for sharing!
