I learned how to do this in college. I am a teacher and this is a different method on teaching multiplication

1. Multiply 2 x 5 = 10

2. Multiply 1 x 5 x 10 = 50 (10 to represent 1)

3. Multiply 4 x 2 x 10 = 80 (10 to represent 4)

4. Multiply 4 x 1 x 10 x 10 = 400 (10 to represent 1 & 4 each)

5. Add up the whole thing 10 + 50 + 80 + 400 = 540

x 43

______

you multiply 25 x 40 to get 1000

then, you multiply 25 x 3 to get 75

add 1000 to 75 and you have your answer of 1075
