>>14315682The primary place you should be doing math is in class.
In the past two semesters, outside of class, I only did the homeworks and studied when there was an exam coming. I had 4.0 GPA for both semesters.
So long as you understand the material in class, you'll be fine.
Make sure to ask all your questions there, including the dumb ones.
>>14315988The idea of the algorithm is to only use doubling, halving, and additions, with no complicated multiplications.
You want to solve 238*13.
>Halve 13 to get a quotient of 6 and a remainder of 1>13 = 2*6 + 1So 238 * 13 = 238 * (2*6 + 1) = 238*2*6 + 238 = (2*238)*6 + 238 = 476*6+238
Now you have a similar problem:
You want to solve 476*6.
>Halve 6 to get a quotient of 3 and a remainder of 0>6 = 2*3 + 0So 476 * 6 = 476 * (2*3) = 476*2*3 = (2*476)*3 = 952*3
Again you have a similar problem:
You want to solve 952*3
>Halve 3 to get a quotient of 1 and a remainder of 1>3 = 2*1 + 1So 952*3 = 952*(2*1+1) = 952*2*1 + 952 = 1904 + 952
Now you're basically done, and have to resolve the additions:
238 * 13 = 476*6+238 = 952*3+238 = 1904 + 952 + 238
