Step 1
Practice doing addition, subtraction, multiplication, and division quickly in your head. About 1/3 of the math questions on the PCAT require you to simplify numerical expressions or solve simple word problems involving proportions. You won't have time to work out all of these problems slowly on paper. The more you can do in your head, the better you quantitative subscore will be.
Review basic concepts of pre-calculus, focusing on functions. What is the limit behavior of a polynomial, exponential, or rational function? What do graphs of these functions look like? Review polynomial factoring as well.
Step 3
Review basic single variable calculus, focusing on derivatives and integrals. Polynomials, exponential functions, and rational functions will be tested on PCAT calculus.
Step 4
Don't worry about geometry, as this will not be tested. You may see a few questions that test your knowledge of sine, cosine, and tangent as functions.
Step 5
Learn to spot wrong answers at a glance. Each PCAT math question only has 4 choices, so if two (or three!) look wrong to you automatically, you'll be in good shape.
First tell me the expression, then I'll tell you what the first step is in simplifying it.
A variable expression includes variables.
algebric uses variables and numerical uses numbers
Numerical expressions solely include numbers, while algebraic expressions may contain a variable like x. An example of a numerical expression is 1+2 and an example of an algebraic expression is 2x+3y=0.

I suggest that the next step should be identifying "this" expression.
Simplifying an expression is getting rid of any brackets or parentheses, performing as many operations as you can - including combining like terms. To evaluate an expression you would substitute the numerical values of all the variables, carry out all the operations (addition, multiplication etc) in the expression to reach the answer - the numerical value of the expression.
There are a few rules for simplifying an algebraic expression. Specifically, one should combine like terms, and then they should try to isolate the variable by doing the opposite, either multiplication or division.

The answer to the question is given in the question!If you want to find the value of an algebraic expression, then you need to substitute numerical values for each of the variables in the expression, and then calculate and simplify the result.
5.8 is a numerical expression.

A Numerical Expression is an expression only using numbers.
Substituting a numerical value for each variable in an expression and then simplifying the resulting expression is known as evaluating the expression. This process involves following the order of operations, which includes performing operations inside parentheses first, then exponents, multiplication and division from left to right, and finally addition and subtraction from left to right. By replacing variables with specific numbers, we can determine the exact value of the expression based on those inputs.
