36•27+36•15-36•42

To solve the expression \(36 \cdot 27 + 36 \cdot 15 - 36 \cdot 42\), you can factor out the common term \(36\): \[ 36 \cdot 27 + 36 \cdot 15 - 36 \cdot 42 = 36 \cdot (27 + 15 - 42) \] Now calculate the expression inside the parentheses: \[ 27 + 15 = 42 \] \[ 42 - 42 = 0 \] Now, substitute back into the expression: \[ 36 \cdot (27 + 15 - 42) = 36 \cdot 0 = 0 \] Therefore, the result of the original expression is: \[ \boxed{0} \]
