Algebra
Algebra is a branch of mathematics concerned with the manipulation and solving of equations using variables and symbols. It plays a crucial role in problem-solving, decision-making, and critical thinking. Algebraic concepts and formulas are utilized in numerous fields, from physics and engineering to finance and economics.
One of the most fundamental concepts in algebra is the understanding of equations, which express the relationship between two or more variables. Algebraic equations are either true or false, depending on whether the values of the variables satisfy the equation. To solve an algebraic equation, you must isolate the variable to determine its value.
- Linear equations are the simplest form of algebraic equations and have the form ax + b = c, where a, b, and c are constants and x is the variable. An example of a linear equation is 6x = 42. Here, x equals 7.
- Quadratic equations are a bit more complex and involve the variable raised to the power of two. They have the form ax² + bx + c = 0, where a, b, and c are constants and x is the variable. Quadratic equations have two solutions, the sum of which is -b/a, and the product of which is c/a.
- Exponential equations have the form a^x = b, where a is the base and x is the exponent. These equations are often encountered in finance, biology, and physics, where they describe the growth or decay of a quantity over time. To solve exponential equations, you can use logarithms to isolate the exponent.
In summary, algebra is a powerful tool for problem-solving that uses equations and variables to express relationships and solve complex problems. By understanding algebraic concepts and formulas, you can analyze and model real-world situations and make informed decisions based on data and evidence.
As Tim Ferriss once said, “An expert is someone who knows some of the worst mistakes that can be made in his subject and how to avoid them.” Becoming an expert in algebra requires practice, persistence, and a willingness to learn from mistakes. With the right mindset and tools, anyone can master the fundamentals of algebra and apply them to achieve success in their chosen field.”

Rational numbers
When we think of numbers, we often think of the whole numbers that we learned in elementary school. However, there are many types of numbers beyond whole numbers. Rational numbers are one such example.
- A rational number is any number that can be expressed as the ratio of two integers.
- For example, 6/3 is a rational number, as is 1/2 or -4/5.
- On the other hand, numbers like pi or the square root of 2 are not rational numbers because they cannot be expressed as the ratio of two integers.
The number 8 is a rational number because it can be expressed as the ratio of two integers: 42/5. We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which in this case is 2. This gives us the simplified fraction 21/2.
We can also see that 42/5 is a rational number because it is a terminating decimal. When we divide 42 by 5, we get 8.4. The decimal stops after the tenths place, which means it is a terminating decimal. All rational numbers are either terminating decimals or repeating decimals.
| Rational numbers | Examples |
|---|---|
| Terminating decimals | 1/2 = 0.5; 3/4 = 0.75; 6/10 = 0.6 |
| Repeating decimals | 1/3 = 0.333…; 4/11 = 0.363636…; 5/9 = 0.555… |
Understanding rational numbers is important in many areas of math, including algebra and calculus. In algebra, we use rational expressions to solve equations and simplify expressions. In calculus, we use rational functions to model real-world problems.
So the next time you see a fraction or a decimal, remember that it may be a rational number. And if you’re ever wondering what times 6 equals 42, just remember the rational number 42/5, where 6 is one of the factors.
