Q1             What are some useful basic mathtricks that most people don't 
know about?

A1           Alex Mazanek   , Studied at Pima Community College Updated 8y

Very simple one I learned in 5th grade that I stilluse to this day that most 
people don't know: what's 4x18? This isn't the mostcomplex problem but it would 
take people at least a couple seconds to solve andsome may have to write it 
down. Instead what is 8x9? Just double the firstnumber and halve the second, 
will give you the same answer in half the time.

My note- I havetried 4 cases and found correct. 

1)   5x16. Doubling firstdigit 10. Half of second digit 8  

(10x 8=80) 

2)  3x 18 Doubling first digit 6, half of second digit 9

( 6x9= 54). 

    3)Seconddigit I have changed so that half of it is with decimal digits  
4x17 Doubling first digit 8 half of second digit 8.5. (8x8.5=68)

  4) First digitI have changed to have decimal  3x24  Doubling first digit 6 
Half of second digit12  (6x12=72)

Q3             Are there any bone disorders thatresult in the growth of extra 
bones instead of the loss of existing ones? Howprevalent are these disorders?

A3             KenSaladin, Author, Anatomy & Physiology—The Unity of Form and 
Function8h

There are two processes in which people growadditional bones, only one of them 
pathological.

Throughout life, people normally develop extra bones,usually embedded in 
tendons near the joints. They’re commonly rounded,pea-sized bones called 
sesamoid bones, but the largest of these, the kneecaps,are present in nearly 
everyone.

The pathological growth of bone tissue in abnormalplaces is called ectopic or 
heterotopic ossification depending on where thebone is forming. In these cases, 
the new bone tissue is often very irregular inshape and may be very painful or 
even disabling.
