A notable product is a special kind of answer that you get when you multiply two or more numbers together. There are some products that are so famous or well-known that mathematicians have given them special names.
For example, when you multiply 0 and any number, the answer is always 0. This is called the "product of 0". Another example is when you multiply 1 and any number, the answer is always the same number. This is called the "product of 1".
There are also some other notable products that come from multiplying specific numbers together. For example, when you multiply two 2s together, you get 4. When you multiply two 3s together, you get 9. And when you multiply two 10s together, you get 100.
So, a notable product is a special kind of answer that you get when you multiply two or more numbers together. Some of these products have special names because they are so well-known and often used in math problems.
