Final answer:
The expression is simplified by adding all the whole numbers together, resulting in 117, as all terms are like terms and there are no variables or exponential expressions involved.
Step-by-step explanation:
Combining like terms to create an equivalent expression is a fundamental concept in algebra, which falls under the category of Mathematics. The question provided requires adding together several whole numbers. To combine like terms, you can simply add up all the numbers, as they are all like terms (being regular integers). Therefore, you would perform the following addition:
11 + 12 + 1 + 6 + 9 + 5 + 69 + 1 + 3 = 117
In this case, there are no variables or exponential expressions involved, so the operation is straightforward addition. This practice of combining like terms is essential because it simplifies expressions and allows one to work more efficiently in solving equations and other mathematical problems.
