Evaluate the Expression: 4 + 2 + 5² Step by Step

To solve the expression $4 + 2 + 5^2$, we need to follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

• Step 1: Calculate Exponents
  In the expression we have an exponent: $5^2$. This means 5 is raised to the power of 2. We calculate this first:
  $5^2 = 25$.


• Step 2: Perform Addition
  Now, substitute the calculated value back into the expression:
  $4 + 2 + 25$.
  Perform the additions from left to right:
  $4 + 2 = 6$
  Finally add the result to 25:
  $6 + 25 = 31$.

Therefore, the final answer is $31$.
