This lecture is just an introductory lecture. There is not any teaching involved. I just tell them about the course.
Explore how to add fractions with like and unlike denominators, find common denominators, multiply and reduce fractions, and identify proper versus improper fractions with practical examples.
Practice adding, multiplying, and dividing decimals with correct decimal point alignment, and learn to find decimals between numbers and relate them to fractions.
Master converting percent to decimal, solving percent of a number, and applying percent change and sales tax, plus tricks for multiplying or dividing by 100 and divisibility rules.
Master operations with whole numbers by applying sign rules, recognizing that negative times negative is positive, and applying the order of operations (PEMDAS) to expressions with exponents and parentheses.
Solve linear equations with fractions by isolating x, using addition, subtraction, and division; clear fractions with a common denominator, then verify solutions by substitution.
Compute slope from two points to write the line y = mx + b. Solve quadratics by factoring or quadratic formula, noting imaginary numbers when the discriminant is negative.
This course is a basic course in math and algebra. It includes percentages , fractions , decimals and algebraic equations. I teach them how to solve an algebraic equation and a quadratic equation. I teach them how to add fractions and how to convert percents to decimals. I show them how to solve a percent equation.
