Consortium for Worker Education - Local Union 3 - International Brotherhood of Electrical Workers Aptitude Test Prep - Part Deux - Math Section

Q: What types of questions are included in the Math Section?

It includes numeric sequence completion, order of operations problems with substitution (PEMDAS), linear equations matching identical expressions, dimensional analysis sign/constraint questions, and inverse function problems that isolate a variable.

Q: How do the order of operations questions work?

They instruct you to plug in given values for variables and simplify expressions following the order of operations (PEMDAS).

Q: What skills are tested in the dimensional analysis section?

The questions use formulas with variables like R, S, T, or e, f, g and ask which statements could be true or must be true based on sign conditions and whether variables stay constant.

Final math practice for the Consortium for Worker Education aptitude test prep for IBEW Local 3. Covers numeric sequences to identify missing terms, order of operations problems using PEMDAS with variable substitution, and linear equations matching identical expressions. Also includes dimensional analysis logic questions with variables constrained by sign and inequality, evaluates statements about linear relationships from given formulas, and practices inverse function questions by isolating variables on the right side.
