What are all the multiples of 3 up to 1000?
There are 333 of them ... way too many to list here. But you can easily construct the list for yourself. Just write down all the numbers from ' 3 ' to ' 999 ' on paper. Then go like this: -- Circle the first number. -- Cross out the next two numbers. -- Circle the next number. -- Cross out the next two numbers. -- Circle the next number. -- Cross out the next two. Keep going like this, all the way down the list. When you're finished, you have 333 numbers circled. Those are all the multiples of ' 3 ' up to 1,000.
