Problem 478 - Prealgebra

Question

Translate the following from math notation to words. $$25+18$$

Step-by-Step Solution

Answer

Twenty-five plus eighteen.

Step 1: Identify First Number

The first number in the expression is 25.

Step 2: Identify Operation

The operation between the numbers is addition, represented by the plus sign (+).

Step 3: Identify Second Number

The second number in the expression is 18.

Step 4: Translate into Words

Combine the identified parts to translate the expression. The expression 25 + 18 translates to 'twenty-five plus eighteen'.

Key Concepts

Addition

Addition is one of the four basic operations in arithmetic. It involves bringing two or more numbers together to make a new total. When you see the plus sign (+), it means you are adding the numbers before and after this sign.

For example:

• In the expression 25 + 18, we add 25 and 18 together.
• In everyday language, we say 'twenty-five plus eighteen,' which means we are totaling these numbers.

Understanding addition symbols and terms is crucial for solving arithmetic problems.

Arithmetic Expressions

An arithmetic expression is a combination of numbers and arithmetic operations like addition, subtraction, multiplication, and division. These expressions allow us to perform calculations.

For example:

• The arithmetic expression 25 + 18 involves adding the numbers 25 and 18.
• Another example is 7 - 3, which involves subtracting 3 from 7.

Arithmetic expressions can sometimes involve more than one operation. But in the case of simple expressions like 25 + 18, the only operation is addition.

Math Notation

Math notation involves using symbols and numbers to represent mathematical ideas. Instead of writing out words, we often use these notations to make expressions shorter and easier to work with.

For example:

• The plus sign (+) is a symbol used in math notation for the operation of addition.
• So, the expression 25 + 18 uses the symbols 25, +, and 18 to quickly convey that we need to add 25 and 18.

Learning math notation helps you understand and solve math problems more efficiently. It’s like a language that lets you translate words into a more precise mathematical form.
