simplify the expression below using order of operations.
$-5^{3} \div (-5) + 1 - 7^{2}$

Explanation:

Step1: Calculate exponents first

$-5^3 = -125$, $7^2 = 49$
Expression becomes: $-125 \div (-5) + 1 - 49$

Step2: Perform division operation

$\frac{-125}{-5} = 25$
Expression becomes: $25 + 1 - 49$

Step3: Do addition then subtraction

$25 + 1 = 26$; $26 - 49 = -23$

Answer:

$-23$
