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 = ???
