## 25 Essential Math Tips and Formulae for BECE and WASSCE Exams

**Number Operations:**

**Order of Operations (PEMDAS):**Parentheses, Exponents, Multiplication/Division (left to right), Addition/Subtraction (left to right). Use it consistently to avoid errors.

**Example:** 2 + 3 x 4 = 2 + 12 = 14

**Factors and Multiples:**Know the difference and how to find them for given numbers.

**Example:** Find the factors of 12. (Answer: 1, 2, 3, 4, 6, 12)

**HCF and LCM:**Understand their meaning and learn methods to find them efficiently.

**Example:** Find the HCF of 18 and 24. (Answer: 6)

**All Algebra Tips and Formulae for BECE and WASSCE Exams**

**Simplifying expressions:**Combine like terms, use properties of operations (distributive, negative signs).

**Example:** Simplify 2x + 3x – 5 + 2 = 5x – 3

**Solving linear equations:**Learn various methods like transposition, elimination, substitution.

**Example:** Solve 2x + 5 = 11. (Answer: x = 3)

**Formulas:**Master basic formulas like area, perimeter, volume of common shapes.

**Example:** Find the area of a rectangle with length 5 cm and width 4 cm. (Answer: 20 cm²)

**Geometry:**

**Angles and their properties:**Understand types of angles (acute, obtuse, complementary, supplementary), angle sum theorems in triangles and polygons.

**Example:** Find the missing angle in a triangle if two angles are 45° and 60°. (Answer: 75°)

**Pythagorean theorem:**Learn it by heart and apply it to right-angled triangles.

**Example:** Find the hypotenuse of a right-angled triangle with sides 3 cm and 4 cm. (Answer: 5 cm)

**Circles:**Know formulas for circumference, area, and understand concepts like tangent, radius, diameter.

**Example:** Find the area of a circle with radius 7 cm. (Answer: 154 cm²)

**All Statistics and Probability Tips and Formulae for BECE and WASSCE Exams**

**Mean, median, mode:**Understand their definitions and methods to calculate them for data sets.

**Example:** Find the mean, median, and mode of the data set {2, 4, 5, 5, 7}.

**Probability:**Learn basic concepts like events, sample space, and use formulas for simple probability calculations.

**Example:** If a coin is tossed, what is the probability of getting a head? (Answer: 1/2)

**Mensuration Tips and Formulae for BECE and WASSCE Exams**

**Speed, distance, and time:**Master the formula: speed = distance/time and apply it to solve problems.

**Example:** A car travels 120 km in 2 hours. What is its speed? (Answer: 60 km/h)

**Volume and surface area of basic shapes:**Know formulas for cylinders, cones, spheres, and apply them to calculate volumes and surface areas.

**Example:** Find the volume of a cylinder with radius 5 cm and height 10 cm. (Answer: 250π cm³)
