Answer 2

Answer:

140

Step-by-step 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
