Divide: I suggest you just switch the decimals to fractions. So 3.5 = 35/10, 4.6 = 46/10. Andddd the same thing occurs.
Sorry i got a bit lazy at the end. Hope i helped, i took a pretty long time to type all these out :/ All the best, and never give up at math! i used to suck SO bad at math, even getting 20+ over 100. But as i got onto secondary school and met algebra, once you grasp the concept and kept practicing ( its the same type of questions really. ) you can do it! i really love math now :) its my favorite subject!
For most applications, simply use a calculator- even at school you can generally use calculators these days. I used mathematics heavily at college and at work, and don't think I ever had to manually do any of these basic operations.
