zero
You multiply or divide the first quantity by the number and then you do the same for the other quantity.
its always the same
If you multiply ANY number by a different number .your answer will always be the same Ex:1x10=10 2x1=2 Even if you do 1x1000000=1000000

For the same reason that you can't divide a number by zero.
you would get the same answer. for example 1 times 3, you would get 3 because any number multiplyed by 1 is always gonna be the same number
There is nothing special about either of those. Multiply them as you would any other numbers.
A negative times a positive is always a negative. The rest is the same: just multiply as if they are both positive numbers and then add the negative sign at the end.
Same as you would square any other number - multiply it by itself.
When ever your multiplying a number by 1 the answer is always going to be the other number NOT 1. For example if I wanted to multiply 1x5 the answer would be 5. This rule goes the same with every number your multiplying by 1.
Scaling is when you multiply or divide two quantities by the same number.
you multiply 27 times a number then you multiply 18 times a different number and see if they come out with the same answer.
