Multiple Choice

Is Noshi correct in saying that when he starts skip-counting forward by tens from 590, both the tens digit and the hundreds digit change? Explain your reasoning.

• Yes, because when he adds 10 more it will be 600 which means both the hundreds place and the tens place changed.

• No, because when he adds 100 more it will be 690 which means both the hundreds place changed but not the tens.

• No, because he added 5 more which means only the ones changed.
