Hello from MrBillDoesMath!

 

Answer:

17


Discussion:

The order of operations has multiplication coming before addition. so the proper interpretation of  5 + 4*3 is:


5 + 4*3 = 5 + (4*3) = 5 + 12 = 17


The Question incorrectly applies  the addition operation before multiplication and interprets 5+ 4*3  as:

5+ 4*3 = (5+4)*3 = 9*3 = 27.



Thank you,

MrB
