Equation problem, simple calculation problem, formula calculation problem, ordinary calculation problem Requirements: 1. The more questions, the better 2. The equation is linear in one variable 3. Don't be too difficult or too easy to calculate 4. Ordinary calculation problems are problems like (67% * 55 =?) [anyway, I don't want this number. I got 57 points, so I sent them all out!)
