What is substitution mean in math?
Answer
Substitution is a helpful process that is often used in polynomials in order to make a "tricky" math problem easier to work with. Substitution simply means that we are choosing to define a variable as a specific value, then plugging that variable in to represent something in a math problem. Oftentimes, the substitution process serves as a placeholder for complex variables like squared and cubed variables.
