# Patterns in multiplication tables

Sal reads a multiplication table, and fill in the missing pieces.

• I don't get this one... A and B becomes 3×3=9 and 2×3=6 that means that A is biger then B?
• Yes. If A = 3x3 and B = 2x3, then A = 9, and B = 6.

Since 9 > 6, we know that in this equation, A is greater than B.
• Why do they use a and b instead of other numbers?
• Because using the variables(a and b) is much simpler than writing all numbers to check if our equation is true
• Aren't multiplication tables a method for helping you understand how to how to do multiplication?
• People often learn using different tools or methods. Some people can imagine the items grouped. Others envision adding the numbers several times. The Multiplication Table is another way of showing the same ideas (counting by 3s or 5s or 6s ...) It is useful because it can help you remember the answer that links to the number combinations. It is also helpful to show that it doesn't matter the order of the numbers (a key concept to remember in the future)!
