Molly and nancy disagree about the value of the expression 2+3×4. molly thinks it is 20 and nancy thinks it is 14.how could
each girl have calculated her answer? who is correct

Molly : she calculated 2 + 3 x 4and she got 20so she basically added 2 + 3 (which equals 5), then multiplied by 4...giving her 20.

Nancy : she calculated 2 + 3 x 4...and she got 14...so she basically multiplied the 3 x 4 (which is 12) and added the 2.

Nancy is correct because in PEMDAS (the order of operations) multiplication comes before addition

221,500 is the answer
