26-(17-8/2) = 8/2 find the greatest common factor,, that is 2.. divide it in the numerator and denominator... so it is equal to 4/1 or 4. then after that, the equation became 26-(17-4) 26- (17-4=13) 26- (13) Multiply it... so the answer is -338 Why -338??? Because positive multiply by negative is negative... my answer in your question is -338
