Super Easy But I Lost Myself

Multiply.
5m(2m - 1)

It's easy, I know what to do, but I can't help the feeling I got it wrong.

That should be easy. What was your result?

I multiplied 5m x 2m and got 10m. Then I multiplied 5m x -1 and got -5m. 10m - 5m=5m
Is it right?

I multiplied 5m x 2m and got 10m. Then I multiplied 5m x -1 and got -5m. 10m - 5m=5m
Is it right?

Nope, 5m * 2m= 10m^2

Thanks

I see where I went wrong now. At least now I can try not to make the same mistake twice. Thanks!
