Like Terms
Like Terms is a skill on Pengi from Lesson 5: Like Terms in Yoshiwara Elementary Algebra.
Key Concepts
Property Like terms are any terms that are exactly alike in their variable factors. The numerical factor in a term is called the numerical coefficient , or just the coefficient of the term.
Examples In the expression $8a + 3a b$, the terms $8a$ and $3a$ are like terms because they both have the variable factor $a$. The term $ b$ is not like them. The terms $5xy$ and $ 2xy$ are like terms. The terms $5x$ and $ 2xy$ are not like terms because their variable factors, $x$ and $xy$, are different. In the term $15z$, the number $15$ is the numerical coefficient. In a term like $x$, the coefficient is understood to be $1$. For a term like $ y$, the coefficient is $ 1$.
Explanation Like terms are terms that have the exact same variable part, including any exponents. You can think of them as being the same 'type' of item, which allows you to group them together through addition or subtraction.
