Math Tips for the entrance exam

Memorize common math formulas before you take your entrance exam. Here are some important ones to know:

Perimeter of a rectangle: A = 2l + 2w or 2(l + w)

Perimeter of a square: A = 4s

Area of a triangle: A = (1/2)bh

Area of a rectangle: A = bh or lw

Area of a square: A = S2

Diameter of a circle: d = 2r

Circumference of a circle: C = 2πr or πd

Area of a circle: A = πr2

Volume of rectangular solids: V = lwh

Pythagorean theorem: a2 + b2 = c2

Average of a set of numbers: Average = Sum of the numbers ÷ The amount of numbers in the set

Commit properties of angles to memory. These five are the ones to know for your exam:

Right angles measure 90°.

The sum of the interior angles of a triangle is 180°.
