Question

Help me with problems 39 a-d

Answer 1

A) -4
d) -3.1
for these questions you have to subtract the two numbers since they have different signs and the biggest sign is the ending sign

Answer 2

Well when you add negative number to a positive number its like subtracting, forget the negative sign is even there and subtract like lets say 1 number was -6.89 and the other one was 3.89 you subtract and if the negative number is more then the positive number you put the negative sign in front so the answer is -3.00 just keep doing that and you should be fine hope I helped :)
