Answer:

Answer is 3

Step-by-step explanation:

For the set of all real numbers we find that additive identity is 0 such that

[tex]x+0 = 0+x =x[/tex] for all x in R

and inverse of x is -x for all x in R

Using this here we want to subtract -6 from -3

Instead of subtracting -3 we can add 3 the additive inverse of -3

Hence

[tex]-3 - (-6)=-3+6\\=+3[/tex]
