Khan Academy

Supporting grades: 7

Description: Learn how to simplify algebraic expressions by combining like terms. The expressions in this video have decimal and fraction coefficients. What I wanna do in this video is get some practice simplifying expressions and have some hairier numbers involved. Like always, try to pause this video and see if you can simplify this expression before I take a stab at it. We have -5.55 minus 8.55c plus 4.35c.
