What property is shown below? 4 × (4 - 3) = (4 × 4) - (4 × 3)

@Cphill, yeah that one! totally knew that! 

Not sure if there's a specific name for it, but it is simply multiplication out of the brackets.

It is a showcase of the rule that

a(b-c) = ab-ac

Not sure what else I can say about it 

It's the distributive property of multiplication over subtraction.......

I sospected that you did......it probably just slipped your mind  .....this happens to me a LOT these days.......LOL!!!!!
