11 times table

Here is the 11 times table.

What do you notice about the numbers multiplied by 11 up to 9?
The number you multiply repeats itself in the tens and ones place of the answer!
But what happens when you multiply 11 by 10, 11, or 12?
10 x 11 = 110
11 x 11 = 121
12 x 11 = 132
A boy thinking
Can you see a pattern in the answers here?
The numbers you multiply by 11 seem to split into the hundreds and ones columns, with a new digit in the tens.
How do you determine the digit in the tens column?
You add the digits in the hundreds and ones columns together!
Does this work for numbers greater than 12?

Example

Example: What is 32 × 11?
Sol: Step 1: Split the main number into the hundreds and ones columns:
32 × 11 = 3 _2
The 3 moves to the hundreds column while the 2 remains in place.
Step 2: How do you determine the digit in the tens column?
You add the digits in the hundreds and ones columns together.
3 + 2 = 5
32 × 11 = 352 

Understanding the Multiplication Table of 12

• Let's explore the 12 times table and uncover its interesting patterns:
  
• Pattern in the 12 Times Table
  • Ones Digit Pattern: The ones column digits increase by 2 each time until it reaches zero, then the pattern repeats.
  • Tens Digit Pattern: The tens column digits increase almost in consecutive numbers.
