First, solve the exponent: $2^2 = 4$. Then, follow the order of operations (PEMDAS/BODMAS): multiplication and division from left to right, then addition and subtraction from left to right. So, $7 \cdot 7 = 49$, and $5 \cdot 4 = 20$. Then, $20 \div (-2) = -10$. Finally, $49 - (-10) = 49 + 10 = 59$.
