To solve the expression \( 15 \cdot 805 + 4(70 - 6) \), we can break it down into two parts:
-
Calculate \( 15 \cdot 805 \): \[ 15 \cdot 805 = 12075 \]
-
Calculate \( 70 - 6 \): \[ 70 - 6 = 64 \] Then calculate \( 4 \cdot 64 \): \[ 4 \cdot 64 = 256 \]
Now we can add the two results together: \[ 12075 + 256 = 12331 \]
Thus, the value of the expression \( 15 \cdot 805 + 4(70 - 6) \) is \( \boxed{12331} \).
