Question

Is -x equal to -1x?

Answer 1

Yes

Explanation:

-1x is a short notation for -1 * x. the "-" can stand for -1

So it would be (-1) * (1) * x

-x is also -1 * x

By the identity property of multiplication, a number x 1 remains the same number.

So it would be -1 * x, which is the same as -1 * x, so they're equal.
