To solve the calculation represented, we simplify it step by step.

The expression provided is:

\[ 1 \cdot 4 + 3 + 5 \div 7 \]

Let's break this down according to the order of operations (parentheses, exponents, multiplication and division from left to right, addition and subtraction from left to right):

  1. Multiplication: \[ 1 \cdot 4 = 4 \]

  2. Division: \[ 5 \div 7 \approx 0.7142857 \]

  3. Addition: Now substitute back into the expression: \[ 4 + 3 + 0.7142857 \]

    First, add \( 4 + 3 = 7 \).

    Then, add that result to \( 0.7142857 \): \[ 7 + 0.7142857 \approx 7.7142857 \]

Thus, the final result of the calculation is approximately 7.71 if rounded to two decimal places.
