A product in math is defined as the result of two or more numbers when multiplied together.
Let us consider the same scenario. You were running an errand at the bakery and had to buy 4 cupcakes. Each cupcake costs $5.
To calculate the total amount you need to pay at the checkout counter, you can add the cost of each cupcake 4 times (as you need to buy 4 cupcakes).
4 cupcakes
So, the answer will be
5 + 5 + 5 + 5 =
20
If you needed 10 cupcakes, you would have to add the cost 10 times.
This is where the concept of multiplication and product can help you.
In the previous answer, you can calculate the cost of 4 cupcakes by simply multiplying them,
You can find the cost as,
4 times 5 or 4 ✕ 5,
You can skip count by 5, four times and get the answer as 20.
