Equations with two variables can be solved when we have at least two different equations involving those variables. This is because having two equations allows us to find the values of both variables. There are two common methods to solve such systems: substitution and elimination (also called opposite factors). In the substitution method, we solve…

Multiplying numbers by 11, then 111, then 1111, with each other results in palindromic numbers—numbers that read the same forwards and backwards. This fascinating pattern reveals the unique properties of these repetitive multipliers and the symmetry they create in the product. Let’s explore this: 1 × 11 = 1111 × 11 = 121111 × 111…

There are many ways to simplify an equation, and the method you choose depends on the form of the equation you are given. Different types of equations might require different approaches to simplification, such as factoring, expanding, combining like terms, or applying specific algebraic identities. Extracting a Number in Front of Brackets When you have…

There are several important mathematical laws you need to understand to calculate accurately. In this session, I will cover most of them, but feel free to ask if you want to learn about any others that might not be included. Mostly common mistake 2 + 6 ÷ 3 = 2 + 2 = 4 because…
