Algebra Formulas for the PRAXIS® Core Academic Skills for Educators Mathematics Test

In the revised “PRAXIS Core Academic Skills for Educator: Mathematics” Test (5733), algebra is no longer as scary as it was. It used to represent 30% of the test, but, as a regular classroom educator, you probably won’t teach complex algebra topics. That’s why the percentage of algebra questions in the revised test dropped to 20%, becoming the third area in importance, after Number and Quantity; and Data Interpretation and Representation, Statistics and Probability.

In the following chart, you’ll find the most essential Algebra formulas you’ll use during the “PRAXIS Core Academic Skills for Educator: Mathematics” Test (5733).

Algebra Formulas for the Praxis Mathematics Test

Category	Formula	Symbols	Comment
Algebra	\(x+a=b \Rightarrow x=b-a\) \(x-a=b \Rightarrow x=b+a\) \(x \cdot a=b \Rightarrow x=b \div a\) \(x \div a=b \Rightarrow x=b \cdot a\) \(x^a=b \Rightarrow x = \sqrt[a]{b}\) \(\sqrt[a]{x}= b \Rightarrow x= b^a\) \(a^x=b \Rightarrow x=\frac{log\ b}{log\ a}\)	a, b = constants x = variable
Algebra	\(a+b=b+a\) \(a \cdot b = b \cdot a\)	a, b = any constant or variable	Commutative Property
Algebra	\(a+(b+c)=(a+b)+c\) \(a \cdot (b \cdot c)=(a \cdot b) \cdot c\)	a, b, c = any constant or variable	Associative Property
Algebra	\(a \cdot (b+c) = a \cdot b + a \cdot c\)	a, b, c = any constant or variable	Distributive Property
Algebra	\(y=mx+b\)	y = dependent variable m = slope x = independent variable b = y-axis intercept	Linear Equation in Slope-Intercept Form. Try to convert any given linear equation to this format.
