Problem 62 - Prealgebra

Question

In the following exercises, translate the following from math expressions to words. $$15 + 16$

Step-by-Step Solution

Answer

Fifteen plus sixteen.

Step 1 - Identify the Operation

First, look at the mathematical expression to identify the operation. The operation here is addition.

Step 2 - Identify the Numbers

Next, identify the numbers involved in the addition. In this expression, the numbers are 15 and 16.

Step 3 - Translate to Words

Finally, write the mathematical expression in words. For the expression \(15 + 16\), it translates to 'fifteen plus sixteen.'

Key Concepts

addition

Addition is one of the basic operations in mathematics. It combines two or more numbers into a single sum. When we want to translate an addition expression, like 15 + 16, into words, we simply want to express each component of the expression in a readable form.
In an addition operation, the numbers being combined are called addends, and the result is known as the sum. For instance, in the expression 15 + 16:

• The numbers 15 and 16 are the addends.
• The process of combining them is called addition.
• The result of this operation is called the sum.

The final step involves writing it in words: 'fifteen plus sixteen.' Notice how easy it is to transition from symbols to words with this process.

mathematical expression

A mathematical expression represents a combination of numbers, variables, and operations. These can be as simple as a single number or involve multiple operations.
In the exercise's example, the expression is 15 + 16. Each expression can be broken down into parts to better understand its meaning and how to translate it into words:

• Operators: The symbols that represent operations, such as + for addition.
• Operands: The numbers or variables involved, such as 15 and 16.

By dissecting the expression into these components, we can understand what it represents. Then, we can translate it into words efficiently. This understanding allows us to visualize and interpret problems more dynamically in both math and real-life scenarios.

identify numbers

Identifying numbers within a mathematical expression is crucial for accurate translation and solving of problems. Recognizing the numbers is the first step in interpreting the expression.
For the exercise given, we start by looking at the given expression 15 + 16. We then identify the individual numbers:

• The number 15 is the first addend.
• The number 16 is the second addend.

By identifying these numbers, we know precisely which values are involved in the addition operation. Once the numbers and the operation are recognized, translating the entire expression to words becomes a straightforward task. The expression 15 + 16 in words is 'fifteen plus sixteen.' Properly identifying numbers helps ensure our translations and calculations are accurate.
