Basic Math Seminar

OSA Chair Bob Croghan frequently says the math you must master in order to answer questions on City civil service exams is “fifth grade” math – in other words, basic math – decimals, fractions, percents, graphs and so on. This fall, Gregory Hinckson, who has served as a trainer for OSA’s exam preparation classes will present a stand-alone single-session seminar exploring basic math. The curriculum will include:

Whole Numbers, including order of operations

Decimals, including converting decimals to percents and fractions

Percents, including finding percent increase and decrease; proportions

Powers and Exponents, including squares and cubes; operations with powers and exponents

Scientific Notation, including converting large numbers to scientific notation

Measurements, including area and perimeter; circumference and area of circles; angle measures and types

Graphs, including bar and histogram graphs; pie charts; line graphs

Word Problems, including solving various types of these problems; using algebraic expressions to solve problems.

If your basic math skills are weak, this is the course for you!

The seminar will be given on Thursday, October 6, 2022. The seminar will run from 6-9pm. To reserve you spot you can download this form, complete it and mail, email or fax it to the union no later than September 29, 2022.
