This is another multiplication worksheet which helps with the early stages of written multiplication.
Multiplying by 40 is the same as multiplying by 10 and multiplying by 4. To multiply by 10 just move each digit one place to the left and place a zero in the units column.
This method reduces this process by placing the zero in the units and then multiplying by 4, ensuring each digit of the answer is placed one space further to the left. There we go!
