Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
Subtraction
Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.

![Priya is comparing two functions: f(x) = 10 · x² and
g(x) = 3 · 2* to find out which one has greater
output values as x gets very large.
She notices that f(1) = 10 and f(2) = 40. However,
g(1) = 6 and g(2)
%3|
= 12. She concludes that as x
continues to grow, the values of f will be greater than
the values of g.
Explain or show why Priya's conclusion is incorrect.
