When we multiply by Zero, the answer is ... zero.
Example: 12 × 0 = 0 Also when the zero is in the front of the multiplication:
Example: 0 × 5 = 0 Or in the middle:
Example: 6 × 0 × 7 = 0 Which can make some things easier!
Example: What is 5 × 11 × 9 × 2 × 0 × 5 × 15 × 25 ? Did you see the × 0 in there? So the whole answer is 0, no need to do the other multiplications Answer: 5 × 11 × 9 × 2 × 0 × 5 × 15 × 25 = 0
But don't get carried away, this only works for multiplies, not adds or subtracts:
