Study notes
- Fractions: find a common denominator to add or subtract, multiply straight across, and divide by multiplying by the reciprocal. Reduce answers to lowest terms (12/16 = 3/4).
- Decimals and fractions: divide the top by the bottom (3/8 = 0.375). Each eighth is 0.125 and each sixteenth is 0.0625.
- A tape marked in sixteenths has 16 spaces per inch. Decimal feet are not inches: 0.4 foot is 4.8 inches.
- Conversions to know: 12 inches per foot, 3 feet per yard, 144 square inches per square foot, 9 square feet per square yard, 27 cubic feet per cubic yard, 25.4 millimeters per inch.
- Area: rectangle = length × width, triangle = 1/2 × base × height, circle = π × radius². Volume: length × width × depth, in the same units.
- A 3-4-5 triangle (or 6-8-10, 9-12-15) has a square corner. The angles of any triangle add to 180 degrees.
- Order of operations: parentheses, then multiplication and division, then addition and subtraction. Round up when you need whole units such as truckloads or sheets.

How to study it
- Practice without a calculator first, then check yourself with a basic one; the Core Level Test allows a basic-function calculator.
- Write the units next to every number; most wrong answers mix inches with feet.
- Take the construction math drill until you score 80% or better: it is the largest module on the test.
