Here are five equations involving numbers in the range 0–3 and the operations + and -:

1. $3 + 2 - 1 = 4$
2. $2 - 1 + 0 = 1$
3. $1 + 3 - 2 = 2$
4. $0 + 3 - 1 = 2$
5. $2 + 1 - 3 = 0$

Would you like me to explain how each of these is calculated?

5 Related Questions:

1. Can these equations be represented visually using number lines?
2. What happens if subtraction is replaced with addition in each equation?
3. How would these equations look if variables were added instead of constants?
4. Can equations with just subtraction, like $3 - 2 - 1$, still stay in this range?
5. What patterns emerge when summing or subtracting numbers repeatedly from this range?

Tip:

When solving simple arithmetic equations, always check the operations step-by-step to avoid sign errors!
