Problem 59 - Prealgebra

Question

In the following exercises, translate the following from math expressions to words. $$5+2$$

Step-by-Step Solution

Answer

Five plus two

Step 1: Identify Mathematical Symbols

The expression is composed of the numbers 5 and 2, and the plus symbol (+).

Step 2: Translate Each Component

The number 5 is translated to 'five', the plus symbol (+) is translated to 'plus', and the number 2 is translated to 'two'.

Step 3: Combine Translations

Combine the translations of each component to form the complete verbal expression. Therefore, '5 + 2' translates to 'five plus two'.

Key Concepts

Simple Addition

Simple addition involves combining two or more numbers to find their total. It's one of the basic operations in arithmetic. In our example, we have the numbers 5 and 2. Adding these two numbers together gives us a total of 7. To perform this, we use the plus symbol (+). For example, we write the math expression as \( 5 + 2 = 7 \). Simple addition is foundational for learning more complex math operations in the future.

• Identify the numbers you need to add.
• Combine the values.
• Write it out using the plus symbol.

This straightforward approach builds a strong mathematics foundation and is applicable in almost every aspect of daily life, like adding up prices or scores.

Mathematical Symbols

Mathematical symbols are the characters or signs used to represent mathematical operations and relationships. In our given exercise, we focus on the plus symbol (+). This symbol tells us to add the numbers on either side of it.
For example, in the expression \( 5 + 2 \), the plus symbol indicates that 5 should be added to 2. These symbols help us write mathematical operations clearly and concisely.

• The plus symbol (+) means addition.
• The minus symbol (-) means subtraction.
• The multiplication symbol (× or \( \cdot \)) means multiplying.
• The division symbol (÷ or /) means dividing.

Understanding these symbols allows us to translate mathematical operations into words and perform them accurately.

Verbal Expression

A verbal expression translates mathematical symbols and numbers into words. This makes it easier to communicate the math operation without writing it out. In our example, we convert \( 5 + 2 \) into words to say 'five plus two'.
Here's a step-by-step way to do it:

1. Identify the numbers. In this case, 5 and 2.
2. Identify the operation. Here, it's addition, represented by the plus symbol (+).
3. Translate each part into words. So, \( 5 \) becomes 'five' and \( 2 \) becomes 'two'. The plus symbol becomes 'plus'.
4. Combine the words: 'five plus two'.

This skill is essential for converting written math problems into spoken language and is useful when explaining math concepts to others or understanding word problems.
