Hi all,
I've worked through the QR section on DAT Destroyer and a few practice QR exams in Math Destroyer. As of now, I'm taking some of the QR quizzes from Chad's website and I notice that all 3 have basic arithmetic questions, usually concerning the square root of some decimal.
I know the calculator on the DAT can be fairly laggy and unreliable, but is it really worth investing the time to learn how to calculate these quickly by hand? I can punch through said problems via mouse much quicker than I can crunch them manually. After seeing so many, it's making me a little paranoid and I feel that I should learn how to do them quickly by hand. What do you guys think? For those who have taken the DAT, does learning how to approximate quickly help, even if you can figure it out quickly on the calculator?
An example problem would be:
The area of a square field is 0.000324 km^2. What is the length of one side?
Thanks in advance for the help!
