\"\"

\

\

The expression is \"\".

\

To simplify the expression follow the order of operations: (PEMDAS)

\

1.      Evaluate the expressions inside Brackets/Parenthesis (P).

\

2.      Evaluate Powers/Exponents (E).

\

3.      Multiply and/or Divide in order from left to right (MD).

\

4.      Add and/or Subtract in order from left to right (AS).

\

A simple technique for remembering the order pf operations is turned into phrase

\

“Please Excuse My Dear Aunty Sally”\"\"

\

First operation is evaluating expression within the parentheses.

\

\"\"                   (Evaluate Power: \"\")

\

\"\"                         (Add: 2 + 5 = 7)

\

\"\"                            (Multiply: \"\")   

\

\"\"                             (Commutative property: a + b = b + a)

\

\"\"                                  (Add: 4 + 112 = 116)

\

\"\"                                        (Subtract: \"\")

\

Next operation is multiplication.

\

\"\"                                               (Multiply: \"\")

\

\"\"
