You need to understand PEMDAS, not just memorize it, to use it correctly.
P - first, do parentheses
E - next, do exponents
The first two are done one at a time in that order. Now we get to MDAS. Here we have two groups of operations. The first group is MD, multiplications and divisions.
MD - then do multiplications and divisions, from left to right, in the order they appear
The second group is additions and subtractions.
AS - finally, do additions and subtractions, from left to right, in the order they appear.
Now let's look at your problem and follow PEMDAS correctly.
[tex] 19 + 14 \div 10 \cdot 4 - 24 = [/tex]
P - there are no parentheses.
E - there are no exponents.
MD - now we do multiplications and divisions, from left to right, in the order they appear. Do one operation at a time per line, so you don't forget to do any operation.
We start with the division 14/10:
[tex] = 19 + 1.4 \cdot 4 - 24 [/tex]
Now we have a multiplication, so we do the multiplication 1.4 * 4.
[tex] = 19 + 5.6 - 24 [/tex]
All multiplications and divisions are done. Now we move on to the step AS. We do additions and subtractions from left to right. We start with the addition 19 + 5.6.
[tex] = 24.6 - 24 [/tex]
Finally, we have a single operation left to do. We do the subtraction 24.6 - 24.
[tex] = 0.6 [/tex]
Answer: C 0.6
