    The solution to the expression (7 + 5) + 4 • 13 – 2 is 62

    How to simplify the expression?

    The expression is given as:
    (7 + 5) + 4 • 13 – 2
    Evaluate the expression in bracket
    (7 + 5) + 4 • 13 – 2 = (12) + 4 • 13 – 2
    Remove the bracket in the expression
    (7 + 5) + 4 • 13 – 2 = 12 + 4 • 13 – 2
    Evaluate the product in the expression
    (7 + 5) + 4 • 13 – 2 = 12 + 52 – 2
    Evaluate the sum in the expression
    (7 + 5) + 4 • 13 – 2 = 64– 2
    Evaluate the difference in the expression
    (7 + 5) + 4 • 13 – 2 = 62
    Hence, the solution to the expression (7 + 5) + 4 • 13 – 2 is 62
