Frequently Asked Questions

What is the difference between multiplication and addition?

Multiplication combines groups of equal sizes, while addition combines separate quantities. For example, 3 × 4 means 3 groups of 4, totaling 12, whereas 3 + 4 means 3 and 4 together, totaling 7.

Can I multiply negative numbers?

Yes, multiplying negative numbers follows the same rules as positive numbers. The product of two negatives is positive, and the product of a positive and a negative is negative.

What is the commutative property of multiplication?

The commutative property states that the order of multiplication does not affect the product. For example, 5 × 3 is the same as 3 × 5, both equal to 15.
