Answer:
140
Explanation:
P: parenthesis
E: exponents
M: multiply
D: Division
A: add
S: subtract
150-(4^2+4)/2 exponent first 4^2= 4*4=16 you do this because it is
inside the parenthesis
150-(16+4)/2 you still have parenthesis so solve that next
150-20/2 next you divide because there is no multiplication
150-10 then subtract because there is no addition
140 is your final answer
