Answer 7

If I had to do it without a calculator:

\[75 = 25\cdot 3\]\[803 = 800 + 3 = 400\cdot 2 + 3 = 100\cdot 4\cdot 2 + 3\]\[\therefore75\cdot 803 \]\[= (25\cdot3)(100\cdot 4\cdot 2 + 3)\]\[=25\cdot 4\cdot 100\cdot 2\cdot 3 + 25\cdot3\cdot 3\]\[=100\cdot 100\cdot 6 + 25\cdot 9\]\[=60000 + 225 \]\[= 60225\]
