7+7-6^2*7

Answer

To solve the expression \(7 + 7 - 6^2 \times 7\), follow the order of operations (PEMDAS/BODMAS):

Parentheses/Brackets - there are none to evaluate.
Exponents/Orders - calculate \(6^2\): \[ 6^2 = 36 \]
Multiplication - carry out the multiplication \(36 \times 7\): \[ 36 \times 7 = 252 \]
Addition and Subtraction - now substitute back into the equation and calculate: \[ 7 + 7 - 252 \] first do the addition: \[ 7 + 7 = 14 \] then subtract \(252\): \[ 14 - 252 = -238 \]

Thus, the final answer is \(-238\).
