Hello i am going to teach you how to solve PEMDAS!
 First, think of a number!
 78 + ( 30 + 5 ) x 5
 Next, solve the number in the parenthesis first before the
numbers outside it.
 78 + 35 x 5
 Multiply it first before subtracting.
 78 + 175
 Then solve the remaining numbers.
 253
 Be sure that the number you are going to solve have close and open parenthesis, have addition, subtraction, and multiplication. You can also use brackets.
 Think of a number again!
 378 + ( 206 + 57 ) x 12 + 35
 Solve the number in the parenthesis again.
 378 + 263 x 12 + 35
 Multply first.
 378 + 3156 + 35
 Solve the addition first.
 378 + 3191
 Solve the remaining numbers again.
 3569.
