What are Variables & Expressions in Math? | Step-by-Step

In this video, we will explore the basic concepts of variables and expressions, and how they are used in mathematics.

Variables are symbols or letters used to represent unknown or changing values in equations or mathematical expressions. Expressions are combinations of variables, numbers, and mathematical operations such as addition, subtraction, multiplication, and division.

In this video, we will take a closer look at how variables and expressions are used in algebraic equations and how they can help us solve complex problems. We will also explore some common expressions used in mathematics, such as polynomials, rational expressions, and exponential expressions.

Furthermore, we will discuss the difference between variables and constants, and how they are used in mathematical equations. We will also cover some tips and tricks for simplifying expressions and solving equations.

By the end of this video, you will have a better understanding of variables and expressions in mathematics and how they are used to solve problems in various fields, such as science, engineering, and finance. So sit back, relax, and join us on this journey into the fascinating world of math!

Can you show a me a formula for a fandom number generator, many years ago
We used basic and I recall using n+1 then cycled back with a return to line 10 restart
Program in the program there was a print then looped pack so we had a 1, 2, 3, 4 ####
But I can’t figure out how to generate random #’s please forgiv me I’m 80
Hope u show and example of a formula that could do this then build a circuit.
I love all your videos watch them daily your a super outstanding teacher !!

I don't think the grouping symbol () is a multiplication symbol, even though we evaluate 2(-2)=-4. Here distributive property could have been used.

Sorry for the mis spell. The word was random not fandom
