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.
- Now, second Step is:
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.

What is the first step for simplifying the expression?
First tell me the expression, then I'll tell you what the first step is in simplifying it.
What is the difference between a numerical expression and a variable expression?
A variable expression includes variables.
What is the difference between an algebraic expression and numerical expression?
algebric uses variables and numerical uses numbers
What is the difference between a numerical expression and a algebraic expression?
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.
The numerical factor of a multiplication expression?

Which options could be the next step in simplifying this expression?
I suggest that the next step should be identifying "this" expression.
What is the difference between simplifying and evaluating algebraic expressions?
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.
The rules for simplifying an algebraic or numerical 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.

How do you find the value of an algebraic expression by substituting a number for each variable and simplifying?
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.
What is the numerical expression for 5.8?
5.8 is a numerical expression.
What is PEMDAS rule?
simplifying numerical expression it means to replace the expression with a value resulting from performing the operation involved in the operation. P-parenthesis E-exponent M-multiplication D-idvision A-addition S-ubtraction
What does numerical expressions mean?
A Numerical Expression is an expression only using numbers.
What is the difference between a numerical expression and a variable expression?
A variable expression includes variables.
What is an example of a numerical expression and a variable expression?
