Answer 1

Solution:

• Let's evaluate this expression.
• Please notice the hint: "Remember the word PEMDAS".
• Here's what PEMDAS stands for.
• P -> Parentheses
• E -> Exponents
• M -> Multiplication
• D -> Division
• A -> Addition
• We do not have parentheses here, but we do have exponents (
  `2^2`)
• 
  `2^2` equals 2×2, or 4.
• Right now the expression is equivalent to
• 4×3-5
• According to PEMDAS, the next operation is M, or Multiplication:
• 12-5
• And finally, subtract:
• 7
