Thank you very much. So with the LARS approach, when you simplify, you are simply moving the decimal place on spot to the right, while subtracting one from the exponent? That is the way it looks...just want to make sure I have it right. THANKS AGAIN.
yeah, technically what they were doing was you multiply one side by ten and divide the other side by 10. but i just think of it as 'left add, right subtract' like you said. keep in mind it works the other way around! you can go 'right add, left subtract' too lol.
examples:
1) using LARS like you described:
100x10^5
=1000x10^4
2) using multiplication of 10 and division by ten with LARS:
100x10^5
100x10=1000 and (10^5)/10=10^4
=1000x10^4
3) using LARS the opposite way: LS RA
100x10^5
=10x10^6
4) using it the opposite way by dividing by 10 and multiplying by 10:
100x10^5
100/10=10, (10^5)x10=10^6
=10x10^6
it doesn't matter what way you choose to do it, but
the important thing to notice is that they all equal the same number. all you are doing is manipulating the numbers so that the expnonents are easier to work with when multiplying, dividing, etc. just practice you will get the hang of it in no time.
ofcourse you can do LARS x2, 3, 4, etc.
ex: 100x10^5
if you move the decimal spot to the right TWO places on the left side ('left add') you must subtract TWO from the exponent ('right subtract')
=10000x10^3
