Could someone please tell me if I got the following problems correct?

1. 7+(-9)+(-5)+6 = -1

2. |-27+14|= -13

3. |-8|+|2|=|-3+2| is this statement true or false? I said false

4. Jean deposited a check for $625, wrote two for $68.74 and
$29.95 and used her debit card to pay for a purchase of $57.65. How has her
account balance changed I got $429.87. That is what the balance would be after the checks and the debit, but I am not sure if that is what they are asking for.

48. -3.4-(-7.6)= 4.2

Thank you so much!

    #2 is wrong

    |-27+14|
    = │-13│
    = 13 (the absolute value of a number cannot be negative)

    check your arithmetic in #4

    625 - 68.74 - 29.95 - 57.65 = ???
