Westside Steve Posted March 10, 2019 Report Share Posted March 10, 2019 Somebody put this on Facebook I think the answer is 4. Am I wrong and if so why? You are my STEM go to guy. WSS Link to comment Share on other sites More sharing options...
TexasAg1969 Posted March 10, 2019 Report Share Posted March 10, 2019 The key is called PEMDAS performed in this order. Parentheses, Exponents, Multiplication, Division, Addition, Subtraction all done in that order left to right. So it is 50 + 50 - 0 + 2 + 2 = 104. The multiplication of 25 X 0 = 0 had to be done before the additions and the subtraction. Link to comment Share on other sites More sharing options...
Westside Steve Posted March 10, 2019 Author Report Share Posted March 10, 2019 So you are subtracting 25 * 0? WSzs Link to comment Share on other sites More sharing options...

And since that equals 0 it really has no effect when you subtract it from 50 + 50. So that equals 100 + 4 from the two added 2s. Link to comment Share on other sites More sharing options...

MLD Woody Posted March 10, 2019 Report Share Posted March 10, 2019 If we are considering this "knowing how to do math" then it is only further evidence that we need to emphasize STEM type subjects more in our country. Link to comment Share on other sites More sharing options...
