When you are multiplying, it doesn't matter which order your number are in.. The rule to follow when you are multiplying by one is anything multiplied by 1 is itself.
If we multiply by 1, then the other number stays the same.
It does not matter if the one comes first, such as i 1 x 8 = 8.
It does not matter if the one comes second, such as in 8 x 1 = 7.
Even large numbers remain the same size when multiplied by one, such as 95 x 1 = 95.
