Important terms to remember

Multiplicand

The number that is being multiplied.
The multiplicand is the number you start with and are making groups of.
👉 Example:
In 4 × 6, 4 is the multiplicand.
You are making 4 groups.

Child-Friendly Explanation:
The multiplier tells you how many times to use the first number.
👉 Example:
In 4 × 6, 6 is the multiplier.
It means each group has 6.
🧠 Think: “How many in each group?”

Product

The answer you get when you multiply.
The product is the total after you multiply.
👉 Example:
4 × 6 = 24
So, 24 is the product.
🧠 Think: “The final answer.”
