# 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)!
• when I watched the video I played it 3 times to understand it
• I dont get it

What Sal is explaining using a multiplication table is basically your timetables as some may call it. It is an easier way to visualize the multiplication table of two numbers together using a column and a row.

Sal is saying that in a multiplication table, where you multiply the row by the column, there are correlations between numbers, many products appear more than once on the table and overall, Sal is teaching you how to use this table. Simply find the two numbers you need or want to multiply, find the row, and move down column by column until you find the number that you want to multiply, and so you will!

In the video, we see the row `4` and column `3`, we know that this means `4 x 3`, but it is not shown, however, `3 x 4`, which is equivalent to `4 x 3` is shown, so we can find the answer of 12. This is a pattern in a multiplication table that we can recognize and use. While there may be some instances where this does not happen, it is very common and is good to know and have.

Hope this helps!
