Worked examples

Demonstration examples with open explanations.

Grade 3

How many centimetres is the perimeter of a rectangle with sides of 4 cm and 7 cm?

Answer: 22

How to reason: A rectangle has two 4 cm sides and two 7 cm sides. Add them: 4 + 7 + 4 + 7 = 22 cm.

Grade 7

Solve the equation 4x + 3 = 19.

Answer: 4

How to reason: Subtract 3 from both sides: 4x = 16. Divide both sides by 4: x = 4. Check: 4 × 4 + 3 = 19.

Grade 10

For which x is 3ˣ = 81?

Answer: 4

How to reason: Multiply: 3 × 3 × 3 × 3 = 81. Therefore 81 = 3⁴ and x = 4.
