The movement of the progress bar may be uneven because questions can be worth mor Which of the following equations is true? \( 1+1=1 \cdot 1 \) \( 2 \cdot 1 \cdot 0=2+1+0 \) \( 10 \cdot 1=0+10 \) \( 4+1=4 \cdot 0 \)

Let's evaluate each of the given equations one by one to determine which one is true. 1. **Equation 1: \( 1 + 1 = 1 \cdot 1 \)** - Left side: \( 1 + 1 = 2 \) - Right side: \( 1 \cdot 1 = 1 \) - Conclusion: \( 2 \neq 1 \) (False) 2. **Equation 2: \( 2 \cdot 1 \cdot 0 = 2 + 1 + 0 \)** - Left side: \( 2 \cdot 1 \cdot 0 = 0 \) - Right side: \( 2 + 1 + 0 = 3 \) - Conclusion: \( 0 \neq 3 \) (False) 3. **Equation 3: \( 10 \cdot 1 = 0 + 10 \)** - Left side: \( 10 \cdot 1 = 10 \) - Right side: \( 0 + 10 = 10 \) - Conclusion: \( 10 = 10 \) (True) 4. **Equation 4: \( 4 + 1 = 4 \cdot 0 \)** - Left side: \( 4 + 1 = 5 \) - Right side: \( 4 \cdot 0 = 0 \) - Conclusion: \( 5 \neq 0 \) (False) After evaluating all the equations, we find that the only true equation is: **\( 10 \cdot 1 = 0 + 10 \)**.
