Ineed with a box method problem i don't know how to do them

Ok for example 12x14

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.

Hope you understand that!?!?!

52 or what they said ☝️
