Any tips on speeding up the basic arithmetic operations like multiplication and division etc?
And that of large numbers? I heard logarithms can be used. If so how?
Dear PowerInside,
In these examples all the calculations are done using logarithms to the base 10.
Suppose you have to multiply, 1245 and 3241
log1245 and log3241 could be found using logarithm tables.
Using a similar method division could be also done using logarithms. In this case you should use the logarithm rule,
Hope this will help you.
if you are not going to do that by the calculator (like wonderboy1953 asked there ) you can check this out Dead Reckonings » Lightning Calculators II: The Methods
or google "vedic math" there you can find a lot of way to speed up your arithmetic operations so calculations will take less time from when you type things in your calculator
