Hey there,
I was wondering if you guys have any arithmetic strategies. I was wondering because I am working problems out of McGraw Hill's GMAT book and it is asking me to do arithmetic problems like 105(Root 3)*37,500.
I learned how to do math going from right to left (the traditional way in our educational system). I recently came across this book (sourced below), which asks the user to do math from left to right. It is technically faster if one takes the time to learn this new system.
Another issue I am having is the number of calculations I am doing on the problems. Some problems, I may do several calculations, which is time consuming.
Here are my questions boiled down:
1) What resources/techniques have you used to improve your arithmetic?
2) Do you use more arithmetic, or guesstimation when solving problems?
3) What advice do you have for me?
Thanks!
