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
