978-(6*8)+99=
978-48+99=1029
Use the order of operations PEMDAS parentheses, exponents, multiplying and dividing left to right, and lastly, adding and subtracting left to right. First, parentheses. 6x8 = 48.  So now we have 978 - 48 + 99.  Its all adding and subtracting, so we can do it simple... 978 - 48 = 930.  930 + 99 is 1029. That's the answer.

1029
