    The problem here is remembering the order of operations.

    P E M D A S

    Parenthesis
    Exponent
    Multiply
    Divide
    Add
    Subtract

    -4^2+52\cdot 5+5^3-(4^2-\frac{48}{4})

    Do everything in that order.

    16+260+125-(16-\frac{48}{4})

    401-(4)=397

    Hi chika,

    I get something different.

    Shenanigans87, your error is in the first term: \boxed{{\color{red}-4^2=-16}}

    -4^2+52\cdot 5 +5^3-\left(4^2-\frac{48}{4}\right)

    -4^2+52\cdot 5 +5^3-16+12

    -16+260+125-16+12

    Evaluate left to right.... \boxed{365}

    um... all signs indicate that the problem suggests the first term is (-4)^2 which is (-4)(-4)=16

    I think you are mistaken.

    Uh....I don't think so. I see no parenthenses in the original problem.
