#-4 3/5#

# - 6 2/5 - (- 4/5) = -6 2/5 + 1 4/5 #

Subtracting a negative is the same as adding a positive.

Think of it this way subtracting is taking away something
A negative is bad so

Taking away something bad is good ( positive)
If you are on restriction no video games because of bad behavior this is negative or bad.

If your mom takes away the restriction ( because of good behavior) that is good ( positive.)

#" " - 6 2/5 + 1 4/5#

# = - 5 7/5 + 1 4/5#

#= - 4 3/5#

The #- 5 7/5# is going down the number line and the #+ 1 4/5# is going up.

They are going in opposite directions so must be subtracted with the direction being that of the larger number.
