write a numerical expression for the verbal expression eighteen more than five
The correct answer and explanation is:
The numerical expression for the verbal phrase “eighteen more than five” is:
5 + 18
Explanation:
The phrase “eighteen more than five” describes an addition operation. The key words here are “more than,” which indicate that you need to add a certain amount (eighteen) to another number (five). In mathematics, when a phrase uses “more than,” it means the second number is increased by the first number.
In this case, “eighteen more than five” means starting with five and adding eighteen to it. So, the base number is five, and the amount being added is eighteen. Writing this as an expression, the number five is placed first, followed by the plus sign (+), then the number eighteen.
It is important to understand that the order in addition does not affect the result because addition is commutative, which means 5 + 18 is equal to 18 + 5. However, the verbal phrase suggests a starting point, “five,” and then adding eighteen to it, so writing it as 5 + 18 matches the phrase directly.
If the phrase had been “eighteen less than five,” then it would involve subtraction and be written as 5 – 18 because “less than” reverses the order of the numbers.
In summary, “eighteen more than five” means take five and add eighteen, resulting in the expression 5 + 18. When evaluated, this equals 23. Understanding verbal expressions and translating them into numerical expressions is an important skill in math because it connects everyday language with mathematical operations. This process helps solve problems involving addition, subtraction, multiplication, or division by recognizing keywords and their corresponding math symbols.
