URGENT: I need to know the answer to this equation and the step by steps: 4 - (-6)
There are a couple more if you want to do them, because I need help with these too:

-10.3 - (-7.79)
-4 + 6 1/2
-10.2 + 4.38
8 5/6 + (-2 1/4)
Thank you.

1) 4-(-6) = 10

2) -10.3-(-7.79)= -2.51

3) -4+6 1/2= 2 1/2

4) -10.2+4.38= 5.82

5)

Step-by-step explanation:

1) A double - equals positive so change to

4+6=10

2) adding positive to negative makes it less negative

3) just change positions -4 from 6 1/2

4) makes it less negative

5) sorry I hat fractions can't do it
