**Addition Settings
1. X+Y = ? (X,Y are defined from number ranges as 0-10, 11-20, 21-100, or 101-200)
2. Add zero: X+0 = ?, X+? = X
3. Next numbers: X+1 = ?
4. Odd/Even numbers: X+2 = ?
5. Add by 1-digit numbers: X+A=? (A: 0-9)
6. Add by 2-digit numbers: X+A=? (A: 10-99)
7. Add by 3-digit numbers: X+A=? (A: 100-200)
8. Add ten: 10+A = ?
9. Sum to 10: A+? = 10, A+B = 10
10. Sum to 20: A+? = 20, A+B = 20
11. Add multiples of 10 (i.e, 10+40 = ?, 50+30 = ?)
12. Add multiples of 100 (i.e, 300+100 = ?, 200+500 = ?)
13. Add doubles: A+A = ?

**Subtraction Settings
1. X-Y = ? (X,Y are defined from number ranges as 0-10, 11-20, 21-100, or 101-200)
2. Subtract zero: X-0 = ?, X-? = X
3. Previous numbers: X-1 = ?
4. Odd/Even numbers: X-2 = ?
5. Subtract by 1-digit numbers: X-A=? (A: 0-9)
6. Subtract by 2-digit numbers: X-A=? (A: 10-99)
7. Subtract by 3-digit numbers: X-A=? (A: 100-200)
8. Subtract all: X-X = 0, X-? = 0
9. Subtract from 10: 10-A = ?
10. Subtract from 20: 20-A = ?
11. Subtract multiples of 10 (I.e, 60-40 = ?, 50-10 = ?)
12. Subtract multiples of 100 (I.e, 800-400 = ?, 500-200 = ?)
13. Subtract ten: A-10 = ?

6. Progress Report
Provides a progress report (as a daily report) for a parent to see how well the children can add or subtract numbers.
