To simplify the expression , follow these steps:
Now, our expression simplifies to , which is simply .
Therefore, the simplified expression is .
Are the expressions the same or not?
\( 3+3+3+3 \)
\( 3\times4 \)
Zero is the additive identity, meaning any number plus zero equals the original number. So and .
Like terms have the same variable with the same exponent. Constants (numbers without variables) are like terms with each other, and terms with x are like terms with each other.
Yes! Addition is commutative, so you can rearrange terms. Many students find it easier to group all constants together first, then variable terms.
If all terms cancel out to zero, that's your answer! But in this problem, we have remaining, so the expression doesn't equal zero.
An expression is simplified when you've combined all like terms and removed any unnecessary zeros or ones. No further combining should be possible.
