How do you evaluate #-7- - 3.75#?

1 Answer

Change both terms to the same form and then add algebraically

Explanation:

#-7 = - 7.00#

# -7.00 - (-3.75) = -7.00 + 3.75#

Subtracting a negative is the same as adding a positive

Think about it this way taking away something bad is good (+)

# -7.00 + 3.75 = - 3.25#

The negative is going down the positive is trying to go up. there is more negative than positive so the negative drags the answer down into the negative.
