    Study Notes

    Translating Words into Algebraic Expressions

    • The primary focus of the lesson is on translating words into algebraic expressions.

    Algebraic Language

    • Algebraic language uses symbols to express ideas and simplify problem resolution.

    Examples of Translating Words

    • An excellent example of translating words into algebraic expressions is converting phrases into mathematical equations.

    Mathematical Concepts

    • Words are not expressed through symbols in algebraic language.

    Physics and Algebra

    • Newton's second law of motion states that the force applied to an object is equal to the mass of the object multiplied by its acceleration.

    Price of Gas

    • The price of gas per liter depends on several factors.

    Algebraic Symbols

    • The symbol 'x' represents an unknown value or variable in algebra.
    • Mathematical symbols such as (+, -, x, ) represent operations or relationships between variables.

    Word Problems

    • Word problems should be translated into algebraic equations to solve them efficiently.

    Lesson Focus

    • The lesson focuses on translating words into algebraic expressions.

    Translating Phrases

    • The phrase 'The price of a car in the US is smaller than the price for the same car in Brazil (in dollars)' can be represented algebraically as US < Brazil.
    • The phrase 'The net income results from the subtraction of the taxes from the gross income' can be represented algebraically as Net Income = Gross Income - Taxes.
    • The phrase 'A discount of 20 percent in any item' can be represented algebraically as Price = Original Price - (20% of Original Price).
    • The total amount of tips received by a restaurant after a month divided among all employees can be represented algebraically as Total Tips / Number of Employees = Tips per Employee.
    • The phrase 'Josh bought 12 pieces of fruit when adding up the apples and bananas purchased' can be represented algebraically as Apples + Bananas = 12.
