noelgreco · Answer

It's all in the order of operations.

Exponentiate, multiply/divide, add/subtract.

$$4^{2}\times4+4-5$$

Just remember: "Please Excuse My Dear Aunt Sally"

It's a mnemonic for the proper order of operations.  The first letters stand for:

Parentheses
Exponentiation
Multiplication
Division
Addition
Subtraction

Actually, the P should be a G for grouping.  " Gotta Excuse...."

We still don't know what Aunt Sally did to require a pardon.
