1. Draw a square and then divid it to four like a t chart
2. When you did that get the 12 and put it out side the square like this 10+2 ⬜️⬜️ ⬜️⬜️
3. Your going to do the same thing but on the left side of the square 10+4
4. Then your going to multiplyeach square by the (first top x left side first) for example 10x10=100 so then your going to write that down inside the first left square
5. Your done but you have to do that with all the numbers.
