$$\text{Zero Error }=-0.03 \text{cm}$$

$$0.06 \text{cm}-(-0.03 \text{cm}) = 0.09 \text{cm}$$

$$\text{Zero Error }=+0.03 \text{cm}$$

$$1.06 \text{cm}-(+0.03 \text{cm}) = 1.03 \text{cm}$$

$$\text{Zero Error }=-0.06 \text{cm}$$

$$6.43 \text{cm}-(-0.06 \text{cm}) = 6.49 \text{cm}$$

1. I think the zero error of the last question is not correct

2. Please I still don’t get how the zero error is gotten when the vernier scale is left to the main scale
