Answer:
3 x 12 - 14/2 + 15
P - Parenthesis
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
In this, the very first two things I see is multiplication and division.
3 and 12 are being multiplied, and -14 and 2 are being divided.
So let's solve for those two first;
3 x 12 - 14/2 + 15
(3 x 12) (-14/2) + 15
36 - 7 + 15
Now we add 15 and 36,
(36 + 15) - 7
51 - 7
= 44
