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.
Addition
Before we begin to understand the addition of algebraic expressions, we need to list out a few things that form the basis of algebra.

![Exercise III: Maximizing profit I
Assume that a company gets r tons of steel from one provider, and y tons from another
one. Assume that the profit made is then given by the function
P(r, y) = 9x + 8y – 6(x + y).
The first provider can provide at most 5 tons, and the second one at most 3 tons. Finally,
in order not to antagonize the first provider, it was felt it should not provide too small a
fraction, so that r > 2(y – 1).
1. Does P have critical points?
2. Draw the domain of P in the ry-plane.
3. Describe each boundary in terms of only one variable, and give the corresponding
range of that variable, for instance "(r, r²) for r E [1,2]". There can be different
choices.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc06c13df-a186-457e-b92c-2ec76adcc88e%2F8c30cdf0-6c44-4398-8d66-912e93453977%2F9tkhmh_processed.png&w=3840&q=75)
