From Ramanujan to calculus cocreator Gottfried Leibniz, many of the world's best and brightest mathematical minds have belonged to autodidacts. And, thanks to the Internet, it's easier than ever to follow in their footsteps (or just finish your homework or study for that next big test). With this installment from Internet pedagogical superstar Salman Khan's series of free math tutorials, you'll learn how to unpack and solve problems requiring you to rewrite and simplify an expression with the distributive law of multiplication over addition.

Distributive Law, Rewrite so its more simple to calculate?
9x25+25=
11x9999=
12x2550=
51x4.9+51x5.1=
I need to learn how?
