MM: Multiplication Patterns
When you multiply a number by ten (10) or hundred (100) or thousand (1000), you will end up having the same number but with different place value.
When we multiply 9 by 10, you're not actually adding a zero; you're moving the digit one place to the left and then, since you can't leave a space, putting a zero to mark the 'units' place.
7 8=56; what about 7 80?
When you compare you notice that 7 is multiplied by 80 instead of 8, so we need to move 56 one place value to the left and add a zero
7 80=560
